Can one or more of the experts in here give me an idea of what I'm looking at here please and how do I get that black stuff off the coin?
A dip would remove some of the dark spots but someone dipped it too many times already. All of the luster is gone.
The 1921 morgan and peace dollars-melt,silver bar-melt,ike dollar hard to tell but if it does have a frisco mint mark it's silver so-melt if not then a spender.The morgan is AU details you could get a little more out of it possibly within the $40 range.The 1934 A note is pretty common and in that condition you could try to get a extra few bucks or just spend it.
Twenty-six dollars and a silver bar. Just kidding. Without better individual full image photos, I'd have to go with the others; melt and maybe a small premium on the note. Good luck.
They're really self-explanatory. On that black stuff, a coin dip will take care of it, just follow the directions.
I think the photos can confirm they are indeed only worth their weight in metal, as others have said.
Silver dollars are worth more than melt. Have any of you attended shows lately? They're selling for over $30 a pop just for culls. Melt value would be about $15.50 at today's (7/5/22) prices. They're worth more than that. The 1922 Peace dollar is by far the most common of the Peace dollars, but even at that, you should be able to get $25 for it.
