Your third piece looks very much like a product of "The American Mint" out of Pa. No relationship to any U.S. government entity. Those actually had an initial purchase price of $79.95 but were later offered for $4.95 in special mail flyers.
What do these off center dimes usually sell for? Coin shop has like 20 of them. Not all 50% off center probably 20% to 50% off center. Just curious! Some of the asking prices are only $5 to $8 Might buy them all lol.
I will say that one with a date and this much off center will bring more than w/o date. How much, I don't know.
