1921 Peace pattern silver coated copper, looking for info

I saw this listed in the Judd book and was wondering if there is any more info about it anywhere. I'm curious if they coated the planchet then struck it or struck a copper planchet then coated it with silver. Also, what was the purpose in doing this instead of using silver? I see the Philadelphia mi...

Re: Found a neat way to measure relief with a ping test and spectrograph

If there are cracks you will notice the coin does not ring as long, if it rings at all. You'll still see spots on the spectograph if you use one, but not lines. Machinists, carpenters, and lots of other trades that work with fast spinning blades or grind wheels will ping them and make sure they ring...

Best resource for satin and matte low relief peace dollar proof diagnostics?

If there's no list of diagnostics anywhere are there higher resolution photos than on PCGS or microscope photos somewhere? Since they were experimental I've heard they ran the dies to failure and melted most of the coins, but hypothetically if the a later die stage coins did survive, that is with no...

Re: VAULTBOX

I despise lootboxes in video games. The only gambling I ever got sucked into was trying to trade stock options and cryptocurrency. I quit that nonsense and definately won't be buying one of these. I suppose CRH is gambling but at least you can only lose time! Now that I think about it perhaps TPG is...

1925-P with a weird font on the date?

I noticed this 1925-P doesn't seem to have the same font on the date as my other two 1925 Peace dollars. I didn't see any VAMs listed that matched it. Is this something special or a known variety? The 5 has a more rounded lower half and the gap on the lower half is wider. The 9 also seems thinner bu...

Found a neat way to measure relief with a ping test and spectrograph

We all know the ping test, whether with a device or balancing a coin on your finger. 90% silver peace/morgan have a fundamental frequency around 4.5khz. Whats interesting is that there are actually two frequencies about 100hz apart because the coin is not a perfect disk, the design breaks the symmet...

Is there a website or database somewhere of auction prices?

I have a few VAMs anacs attributed that they've only attributed a dozen or so of. I don't see how to browse pop reports for all of them so I don't know the relative rarity or desirability. Searching ebay / heritage / stacks / great collections didn't turn anything up. Is putting them up for auction ...
