From the "Annual Report of the Director of the Mint" for 1950 available on the Newman Numismatic Portal at: https://nnp.wustl.edu/library/book/341 Page 53, Domestic coins, including assay pieces, withdrawn from monetary use during the calendar year 1949 Below is the column for individual purchases, there is a separate column for coins received from banks. The mints paid face value for the coins including gold coins and trade dollars. I calculated and added the "number of coins". Denomination, Purchased (face value), Number of coins Gold $3, $15, 5 Gold $1, $30, 30 Silver trade dollars, $4, 4 Silver 20-cent pieces, (zero) Silver half dimes, $0.10, 2 Silver 3-cent pieces, $0.03, 1 Nickel 3-cent pieces, (zero) Copper 1/2-cent pieces, $81.03, 16206 (Somebody had a lot of 1/2 cent pieces) Only worth a dollar? In 1949 yes.
Well, duh. Why would you sell your 20-cent piece to the Mint when you could pass it off as a quarter? @Inspector43
