So, if you have some PCGS-graded coins that you want in the NGC registry, better do it now. There are probably a few collectors who were planning...
I would guess you're right. Try coating a Morgan dollar with a clear coat and send it in for grading. Probably would come back in a bag. Cal
Putting a bit of sacrificial metal, usually copper, in a container of coins assumes the reactive gas molecules, like hydrogen sulfide will go the...
My approach is basically the same. I look at SB auction results and at recent auction results in Coin Facts too. I find prices in PCGS and NGC...
At one of the Long Beach shows last year, I wanted to look up the value of a couple of coins to put on a PCGS submission form. I didn't have a...
All bank bathrooms should have one! Actually, imbedding in or coating with a clear inert medium might work really well. Ancient and medieval...
Vacuum has to be the very best way to store coins. Practically no oxygen, hydrogen sulfide, or water vapor. However, the vacuum has to be...
Most of these coins are now PCGS-certified. However, the PCGS pop report exaggerates the number of coins that exist. For example, one particular...
Thanks loads, Dave. I was not even aware of the PCGS auction prices web page. I had looked at the registry and coin facts, but there were a few...
I've been doing research to catalog 1864 small motto two cent proofs. Probably fewer than 20 exist. I've been able to identify 13 unique coins...
I've never bought a coin from Rich, mostly because he doesn't carry much of what I collect. However, I have bought books from him and found him...
Anyone have any knowledge or experience with the stability of anodized niobium? A few mints, like in Austria and Canada, are using anodized...
Don't clean your coins unless you use a very special brush. Ran across this ad in the Numismatic Gallery Monthly. Wonder if the Swiss still make...
Very interesting coin. Thanks for posting it. Handle the slab gently. That 3-point mounting looks a little precarious. It could turn into a...
You're right that money bought votes in the Roman Republic. However, the moneyers, being young guys, didn't usually have much independent wealth....
More expensive. Oh yeah! Back when I collected ancient Greek coins, they were out my reach. Some of the most beautiful coins ever. Easiest way...
Nice coin @Mikey Zee ! I collect Republican coins, but I do have one imperial coin. It's a hippo coin of Otacilia Severa, Philip's wife. There...
From the photos, sure doesn't look 65+ with CAC. May be a case of photography exaggerating the dings. I've noticed in playing with lighting and...
OK, bear with me if you are familiar with Roman Republican coins already. In the Republic, the mint was supervised by magistrates (usually...
Nice post. There is one variety of the 1941 proof missing the AW. Believe it was polished off the die. Cal
