@Conder101 literally wrote the book on slabs. If anyone knows he would - and if he doesn't know about it yet, I'm sure he'll want to. He keeps...
QDB relates in one of his books that this exact same concern was written in an article in the Numismatist in 1913. I can't remember the exact...
Everyone was at fault, except the step-mom. John should have done 2 things better: he should have trained his family on the importance and value...
I have it broken down into categories, but then each coin gets the next sequential number. This is very similar to how museums catalog their...
In my tracking spreadsheet, I assign each coin a serial number. I then name the picture with that serial number obv and rev. That way, if for...
For everyone besides Doug - go get a few modern coins out of your change jar. *Closely* examine the surfaces. Apply acetone in your preferred...
Why should it be graded using tougher standards? Aren't the standards the standard and should be applied the same to all dates? If you are...
Yes, I have seen that too. And, it is due to the temperature change from evaporation. Basically, now the coin is colder than surrounding air, and...
Oh, yes, good call! I always use a pad under the glass container. I have a soft cloth that I do all coin work over, and then I'll layer several...
I use a small glass pyrex dish, like you would serve pickles in or something. Basically, anything glass that's big enough to hold your coins. Just...
Nail polish remover isn't usually pure acetone. Often, it will have other chemicals and perfumes added. The denatonium itself won't harm the...

That's one that I can't answer. Do we have any experts in contemporary counterfeits here? I know that some of them can actually be quite valuable.
No idea, but that die is *shattered* That's really cool.
Absolutely looks fake to me. Compare it to genuine examples here:...
Can I go again? I'm going to go again, because I have too many favorites. The first is a Franklin that I bought as 65FBL, but then got upgraded...
If you own the reference for that series, how does the coin you are looking at compare to the plated coin?
Wow, you really are tough on coins! I think its a solid 64. Clean fields means it's better than a 63, too much face chatter for a 65.
It's a service NGC calls "appearance review." Last year I sent them a coin that was labelled wrong, and they fixed it free. I also sent them 3...
