After 2 hours of tedious blow torch experimenting and 20 min of trying the different wire brush wheels I have (brass and steel), and watching many videos on how acid reacts to different metals (mostly copper) IMHO its not any of those. And please explain how a rotating wheel\brush can create doubling,tripling and more, it doesn't IMO, but if it did could someone show us an example?
However I do know that this could be done by using an acid etching method I seen in a video, although it would be really tough to do and require a lot of talent (like a trendy hobo nickel talent) and I don't believe this to be the case.
I would like to point out that most of these coins all have the same look. Why would that be? This happened to both sides of the coin without ruining the opposite sides. I think it happened all at once.
Well generally speaking DBM what if a planchet already had something like that on it before it entered the striking chamber, what would it look like?..not like a grease strike thats for sure. Don't get me wrong my first observation I thought PMD too as we have seen these here before...just trying to figure it out thats all.
@ nss-52 I'm well aware of that, my comment was intended as a joke to lighten up the mood of the OP. I myself have made 2 regrettable purchases in the past both times I should have asked the seller for more info or pics...anyway I learned my lesson too so I know what it feels like.
I think you'll be ok in the long run just put them somewhere for now and move on. Lets face it if the price of silver goes much lower we might as well use it to mint coins...lol..it will rebound in time.
I agree its not a blow torch wire brush or acid. If it was struck through anything then I would say..not a sponge but hydraulic fluid. The high grade fluid used in a press is capable of moving metal as it tries to escape the force of the strike. Frankly hydraulic fluid is seldom if ever mentioned on error websites and I'm not sure why as its in every press and a leak would easily cover both dies if leaking from above the hammer.
You can't always believe your LCS. I see zero errors on your coin, how could you have die cracks not pictured..? we can see both sides of the coin so if there are cracks they must be near microscopic. As mentioned the scratch on the 'T' is obvious. The only reason the toning is different in those areas is because of the age of the coin compared to the age of the scratch.
I could easily duplicate what I see in your pics, it really wouldn't take too much effort and that includes the color differences. Just my opinion
If it was struck through copper flake then IMO the copper was on the planchet before it was struck thus the rim looking nick. Here are a couple other coins struck through with copper...http://goccf.com/t/161264
