The toned Kennedy silver art bar was minted by the Madison Mint in 1985 and it is part of the Presidential Cameo set. I like that rainbow toning. That looks cool to me. EDIT: Oops!!! I think the image on the right is part of the Kennedy silver art bar on the left. I deleted a paragraph because I thought that it was a separate silver round. Sorry about that. The last silver bar of the Madison Mint Presidential Camro set was the Ronald Reagan silver art bar.
What would something like this be worth? Would there be a premium for the toning like you find for many coins? Chris
It is possible but most of the time, a silver bar like that might sell for between $4-$7 over spot silver on ebay. On most silver art bars that I have seen on ebay, toning does not play a large part in the winning bid for silver art bars. "Rarity values" will usually play a very large role in what a person will pay for a silver art bar on ebay. A lot of these silver art bars are old '70's silver art bars that had low mintages (mintage of 1000 or less) to begin with and it is hard to determine of many of those low mintage silver art bars were melted down during the early '80's. I have seen a lot of low mintage silver art bars sell for $10-$20 over spot on ebay. I have seen some silver art bars sell for $100 (or more on ebay). It really depends on the silver art bar. The silver art bars such as the one that you posted is probably a mid to high mintage bar and they are not usually hard to find on ebay. If they are found locally, then a local dealer might charge a .999 generic silver premium for it. On ebay, it will more than likely sell for between $4-$7 over spot.
