How much is the 1945 Harry S. Truman bronze coin worth?
This sounds like a commemorative medal, perhaps the
"Inauguration" medallion after assuming the Presidency upon the
death of Franklin D. Rosevelt. As such it has no numismatic value,
as it is not legal tender. It probably does have "book value" to
collectors of Presidential medals, but I'm unfamiliar with price
guides for that. (Other FAQ Farmers can edit this last bit to
substitute an accurate value. :) )
