The story
Struck for Washington's 200th birthday in 1932 and intended as a one-year commemorative, the design simply never left. Silver Washingtons are the most-recognized junk-silver coin, and at 90% silver each carries about fifty times its face value at current spot — the single clearest illustration of what happened to the dollar after 1964.
The 1932 'commemorative' has now outlived every regular design it was supposed to interrupt.
