I have a hoard of around 100 pounds of copper pennies, all out of circulation and am wondering if there is a chance any might have a doubled die out of that big number. I will check some of them today.
I think the odds are very good. However, I think your eyeballs will fall out of your head before you finish searching them all. That is not a task I envy you.
Anything is possible. My only request is that you please don't post photos of the other 9,999 that are machine doubling. Chris
8000 threads of LOOK WHAT RARE ERROR I FOUND IN THE BULK LOT incoming! Haha! Just teasing you coinman1234
I read that a guy invented a device to put in cents and look at them one by one but this device would drop the coins you did not want and keep the ones you want to save and take another look at. ??
If I were to attempt such a thing, (I won't), I would get one of those magnifier lamps that attached to the edge of a desk. Then its just grab a cent, look, and discard. Picking up one cent, holding a magnifier, seems very laborious.
I went through 200 and found a no "FG" intial error due to overpollishing I'm looking carefully with a flashlight and a loupe on each side carefully. Not just doubling, but any errors are great.
yes, about 50 years ago, it had a slot to insert the coin and a mirror and lens combo showed both sides of the coins at the same time. You could then eject the coin into a save drawer or a spend drawer. They occasionally show up on eBay, but they are hard to find as the bronze vs. zinc sorters dominate in the listings. The 2 I have seen went for over $50. I have also seen one homemade with a stereoviewer and mirrors in some coin mag from the 60s.
100lb * ~150 = 300 rolls, yea that is doable. You said copper, are the mostly 1959-1982? Are they pre-sorted by date? I don't know your level of variety checking - if you know most of them by heart, then I do slight magnification and check each cent front and back, then put it in my coinstar box if I see nothing. Anything I see that has potential gets set aside to look through with a loupe. If you don't have the biggies memorized by year, and you really want to go through everything, I would sort them by year. Then review the RPMs, Doubled Dies, and varieties by year/mintmark then go through those specific years while you know what to look for is fresh in your head. I like to keep anything with die cracks, laminations, or anything which looks off to study later as well, not just the known things. You never know what you will find from circulated coins, could be nothing, could find some previously discovered treasures, or could find something completely new.
You don't need to pre-sort or have any list memorized. You just need to know what an RPM or DDO/R looks like. Once you've identified that the coin is a DDO, you can match it to the pictures and attribute it.
Very true if you're just looking for RPM/DDs, I didn't mean to make this more complicated than it should be. For me, those are easy to spot. Things like the different mintmarks, initials, large/small, which years to focus on the eye, etc are always nice to have known before I start looking (things that may not be evident just by looking). I guess since he said they're just copper, that leaves a lot of zinc varieties out where a book would help.
Just for fun I went thru about 50 cents sitting on my desk and a no fg on a 1970 d cent?? These must be common ?
