My first thought would be to question the purity of the acetone used. My second thought would be that the acetone reacted with something ON the...
Here's my chance to get my knowledge expanded. "Deionized" vs. "Distilled" To me distilled means all non-water matter has been removed. (We...
Given time the organic acids in the fingerprint will etch the coin's surface. It takes a while but it will happen. That's why you can have...
You beat me to this answer. ;)
Since I now have about 27 IHCs I decided to try to attribute them. So I pulled down my copy of Snow's attribution guide. I happened to have my...
ICCS is the ONLY one I know of. The contact info is here: http://coinauctionshelp.com/ICCS_TPGS.html
IMO ASE's have the same problem, just not to that degree. ASE's are bullion coins and to pay more than a couple bucks over spot is wrong. Unless...
My dream coin would be a 1907 High Relief Double Eagle. I need it to complete my NGC Gold Registry Set.
I stopped by and had a short chat with a couple of the CoinTalkers. One was The Penny Lady and the other 900Fine and his wife. There was the...
IMO start by sitting down with a reasonable price list such as Numismedia (it's online; use Google to find it). Look it over and decide what...
I'll be there Friday morning as usual. You are now on my list. Looks like The Penny Lady will be there also.

I used to have a full set of UK circulating coins issued during the reign of KGVI. Long gone now.
My criterium for 3-cent nickels is on the back. I look for ones which have ALL the vertical lines in the Roman numeral. I saw an MS-66 once that...
Wow! Nice! A bit ambitious collecting a gold coin issue. But probably profitable in the long run. Keep it up.
No. Ignoring the error varieties, the only Washington quarter keys are '32-D and'32-S. It might qualify as a semi-key.
I would personally think of it as a hobby, not a profitable vocation. Just like numismatics is a hobby, not an investment. Naturally there are...
NICE COIN! The "arrows at the date" type was only struck for 3 years. I agree with AU details. Can't tell about luster or possible cleaning....
Actually it's just the reverse. It's one of the more reactive metals. That's why it's used to coat steel (galvanized). Zinc will protect the...
I remember speculation about how the 1980 silver bullion spike affected coins. The thinking was that common dates might not that common anymore....
