I had the privilege of photographing many coins in his collection. I posted a photo tribute a while ago on the PCGS board. I'm pretty sure some...
The copper layer will degrade as soon as it's exposed to a harsh environment, and eventually let the catalyst to the Cu-Zn interface. One...
Any corrosion inhibitor needs to be between the copper and zinc to prevent galvanic corrosion. A "coating" on the coin may prevent an external...
Yeah, I already turned the brightness down a bit from the factory setting so that everyone wouldn't see my pictures as being too dark. While I do...
Zinc is much more anodic than copper, so in the presence of some sort of catalyst (humidity, sweat, etc.) you will get some nasty galvanic corrosion.
Bought a Dell P2715Q 27" 4K monitor and it arrived today. Holy crap, is this thing sharp! And huge! I can be using Photoshop on half the...
If I were imaging a bunch of < $10 circulated silver coins in low circulated grades (G-F), I'd be tempted to do it this way, since it's quick,...
I'll bet there's configuration that can be done to fix the exposure and color of the Epson scan. Much better than the HP. Here's a scan off my...
The forum sort of takes care of that by itself. Ask a question to everyone in the forum that's the closest match, and if the specialist you seek...
A coin can be fully struck and still lack detail due to a die that is either missing detail due to wear, hubbing, or a hub that's missing detail.
Some do. It depends on perceived demand, mintage limits, and ordering limits. I've had someone offer me profit on this and the 1 oz. proof...

Got mine ordered and sold. Obscene profit, no, but an easy profit.
1954-D. It looks like the text on the facing page was for the quarter albums. You can see the start dates of 1916 and 1932 near the bottom of the...
B-31/BB-115 is supposed to have really weak stars. The big divot in the field where the stars should be is probably the damage that's given on...
Looks AU50.
I was at nice 67 for the OP coin. You can't really experience 68-ness of a Morgan from a lifeless picture. I'll bet a dollar to a donut that CAC...
The dies, no, but detailed photos of the dies and hubs. TPGs have authenticated forgeries in the past, so I would expect that authentication of a...
The Mint has working 1964-D Peace dollar dies that have been closely studied to the extent that it will be possible to authenticate such a coin....
I saw this on the PCGS board and was stunned. I had known Mike for several years and had the chance to photograph many of his coins. He had a...
