    yup it goes year, mintmark and then mintage under that, and a little more info on the coin as a whole on the paper that folds out on the 3rd section, let me know what else u need, i have a great deal of folders from them (modern circulated, Mercs) You gotta get the 20th Century, that is fun to complete-Lincoln Mem and Wheat (regular and Steel), Indian head,---- reg jeff,silver jeff, buffalo,(mabye liberty head, but im not sure)---- merc, reg roose,silver roose,----reg Wash,bicentennial , silver wash, SQ, Standing Liberty, Barber,-----WL,Frank the Tank,Kennedy reg and Silver, Barber, Bicentennial,-----Now for my favorite part-----Peace, Morgan, ike,bicentennial too , SBA, SCA.

    Its not in that order though, and its hardly expensive at all, I might of missed a couple but i highly doubt it

    Hi GDJMSP,
    What is the best way to avoid hairlines when putting a coin in say an intercept holder?- that is a tight fit for a 50c piece and pressure must be used. I put 4 uncirc frankies into that intercept sleeve using pressure on a fine weave cotton cloth-is it llikely I hairlined them?
    Thanks!

    To be honest I have never tried using one myself. I own slabbed coins in Intercept Shield - but not the kind you use your yourself.

    I would imagine though that they are similar to the Coin World holders. The way you use those is simple. Place the coin on a hard surface, table or whatever. Then holding the flexible black insert so that it is bent in the center, place one edge of the insert down over the coin. Then lower the other edge down over the coin as well. Then place the hard case next to it on the table. If properly sized, the insert should hold the coin well enough to pick it up without touching the coin with your fingers. Place it in the holder, close it up - all done.

    Now - did you leave marks on your coins by using a cotton cloth to press them into the holder ? There is no guarantee you did - but probably so. It really doesn't take much. :(

    That's the part that scares me.

    Not if you think about it. Consider - what surface would be more likely to mark a coin when placed on that surface - a piece of cloth with hundreds of threads to rub against the surface of the coin - or a smooth hard surface like a table ?

    The whole business of scratching coins baffles me. When I took geology in high school, we learned of a Moh’s scale of hardness. Items of hardness 10.0 would scratch items of hardness 9.0 if you rubbed them together; hardness 5.0 would scratch 4.0 (or 3.0, 2.0, etc.). You couldn’t scratch a diamond (10.0) with talc (1.0). Or anything else, except another diamond.

    Gold and silver are evidently 2.5 to 3.0 on the scale:

    http://www.amfed.org/t_mohs.htm

    which is fairly soft.

    As a coin collector, I’m learning that metal coins can be scratched by rubbing them with cotton. Putting the coin down on a hard surface (almost certainly harder than silver) would seem to me to be disastrous if the coin slides along it.

    I understand your point, but as I said - think about it. Visualize in your minds eye what is actually happening in the two situations.

    When you mention hardness - would you agree that you can take a soft cotton cloth and wipe it across the surface of coin that you will leave marks and/or hairline scratches ? I'll assume you will agree. Now why does it leave scratches if the metal of the coin is harder than the cloth ? Well when you're thinking about the hard metal of the coin you're forgetting something - the luster.

    If you were to take an Unc coin and cut it in half so that you could look at the cut edge - what would see ? On the surface of that coin you would see small, shallow ridges. And if you were to magnify them greatly they would look something like this - /\/\/\/\/\/\/\ It is those ridges that produce the luster and cause the light to reflect.

    Now if you were to take a cloth and wipe it across the top of those ridges - would they be as hard as a piece of the same metal that was smooth ? No they would not because they are quite thin - almost like fine wires on the surface of the coin. So when you wipe a cloth across them - those wires break and the breaks look like scratches.

    Now then, on a soft surface like a cotton cloth, the coin sinks in allowing more of the surface of the coin to be touched by the fabric and the fibers of the cloth. And if there is any movement the cloth will scratch the coin.

    But on a hard, smooth surface like a table or countertop - only the high points of the coin actually touch the surface. And the less surface area of the coin that is in contact with the surface under it - the less chance there is of leaving marks.

    The key in both cases is to not let the coin move. But in all likelihood it will somewhat. And if it does - which would you rather have - the surfaces in contact in many places as with a cloth - or in only very few as with a table ?

    Does that make sense now ?

    An excellent answer. If I understand what you’re saying: the secret ingredient here is the luster. As you’re describing it, the luster is a radial network of delicate ridges which, when rubbed with something softer (or harder), are getting broken down and/or crushed (and not technically “scratched”), but the appearance is that of scratches because of the patterns of the broken ridges.

    I feel better now; my geology teacher wasn’t lying to me. :)

    All of this implies that a coin without luster would not be “scratched” by a soft cloth in the way that a coin with luster would be. Am I still on the right page here ?

    yup i learned that Moh scale too but its not to scratch a coin with a cloth like GD said

    Well yes and no. Coins, because of their nature are never really smooth. The metal will always have microscopic ridges. That's why they say to never clean a coin. But just touching it with a cloth will certainly be less noticeable.

    I am a big fan of dansco albums, I am using them for everything from statheood quarters ( including proofs ) to my growing collection of choice BU early commems...
    I know that people warn about slide-marks etc. but i don;t have a problem. The trick is to take your time, go slow, etc. I wear white coton gloves, use an air can to blow any loose particles from the album hole, gently seat the coin in the hole ( very, very, carfully ) Make sure to check for clearence so that the mylar slide doesn;t make any contact with the coins surfaces when you slide it into place...

    I also try to do a "row" at a time, I wait untill i have enough coins to fill a whole section of the page, this limits the amount of times that the coins have a risk of being damaged, the less you handle a raw coin the better...

    just my 2c

    RanchHand, do u have a problem w/ proofs hair lining in the dansco?

    not that i have seen, i am SUPER careful, the only thing that comes in contact with the coins surface is air ;)
    I am working on a vacume tube big enough to fit in to fix that problem ;)

    JK

    I try and go slow, anjoy putting the coins in the album, its like a ritual. If you take your time and go real slow and methodical you should be OK. If you want "practice" try it on cheaper proof coins or loose coins, as long as the surface of the coin is underneath where the slide is you will not impart hairlines, be especially careful if you need to remove a slide that has a coin underneath it.

    I think thats where most slide marks come from, the person was careful putting the coin in but did not check to make sure it did not move up into the holder, when the slide is removed WHAM... slide marks! Before i remove a slide that has coins underneath it i check each coin. The best this you can do is wait to get a complete "row" done, and do them all at once. If you do it one at a time you are exposing the coins to the chance of slide-marks ever time you put a new coin in...

    Hope that is some help!

    But how do you push the coin down into the hole in the album without touching the surface of the coin ?

    sorry to resurect this thred, i was just digging through some old posts and notice i did not respond to your question GDJMSP

    When placing the coins in the album i first wear clean cotton gloves, I hold the coin by the edge at all times, I use compressed air to make sure that the album hole is clean ( i usuallt blow off the coin as well to make surte it has no residual dust on it )

    1. tilt the coin in starting at its edge.
    2. "walk" tha coin down into the hole, the only pressure that is applyed is on the rim
    3. once the coin is fully seated make sure it is below where the slide come over it
    4. replace front slide, if any resistence is felt pushing the slide in the coin is not far enough back, press the rims down and try putting hte slide in again.

    one of the keys to this process is to try and fill an entire row at a time, I beleive most slide marks come from opening/closing the slide repeatedly as you fill in more holes.

    or you can use magical powers, whatever is easier for you ;)
