So update if anyone is interested. ICG notifies me its on its way back and is a “90” which I assume means it is 20 points better than perfect so, WINNING!!!!!!! Actually I think 90 is their code for “damaged” which was expected. The authentication was all I wanted and that seems good to go.
Without the Slab # I cannot be specific. "90" covers lots of options. Usually it means we cannot be 100% positive that the coin is genuine. That chemical bath must have really etched the surface enough to make is look suspicious (if that was the reason for the 90). Of course, you know the coin is 100% genuine. If I were you, I'd send it back in to ICG or any TPGS with a link to this site. It will be worth more in a slab.
Ah, just found my way back to this thread after someone revived another "restoring silver dates" thread. I somehow missed the resolution from the TPG. I wonder if the TPGs are concerned that an unscrupulous chemist could "raise" any arbitrary date on a coin this way? I can think of ways to do that -- but they would apply equally to Buffalo nickels, and those do get certified even after acid "restoration".
I decided not to resubmit the coin, and threw it on ebay as-is, with explanation and photos. Sold for about what a poor details level graded coin would have.
If it's the one I'm looking at, you put it at true auction (good move), and 24 bids later, it went for... considerably more than melt. So, now I'm back to wondering why we don't see them (restored-date SLQs) more frequently...
The makers of NIc-a-Date might want to invest in bringing back their old product Nic-a-Silver. I know I would buy it.
That's probably the one! I was very much "let the market" decide mode. I think I started it at 99 cents! I was very happy with the final price, and I think the buyer was happy as well. I like it when everyone ends up happy. Ironically, the guy who eventually won it private messaged me on ebay offering me MORE than it sold for to end the auction early. So in the end he saved a bit of cash too
