Technically it's still an ounce of silver but you'll definitely get a couple of dollars less for it when you sell it. Basically, your test cost you but I'm sure you knew it would! Definitely not garbage!
Well heck with silver at around $24/ozt right now I would be happy to know if I could get $20 for it. Basically I just was checking to see if acid testing completely devalued it to nothing but like you said it’s still an ozt of silver.
Nah I’m just using it as a test subject or cull for whenever I want or need to do something that requires silver. As damaged as it is I would hate to have a hole in it. To me a hole in a coin is worse than acid damage.
