Which is silly because MOST Unc dollars sat in the original bags until the early sixties so the difference in time in the bag for the typical Unc Morgan and the GSA dollars is about six years. (The vast majority of Morgan dollars did not come out of the vaults and into the public's hands until the rush on the Treasury 1962 - 1964. If you look at the figures for the stock of dollars on hand and the draw down rate you find that during that period something like 180 million silver dollars came out of the Treasury. and almost all of them had been in the vaults since they were struck.)
