norm for business strike Jeffersons sometime around 1990
I believe a new master hub in 1987 made FS Jefferson the normal strike, so they are common from that year to today. I personally save all FS examples prior to 1987.
As correctly noted above, there are some dates in the mid-1950's through the early 1970's where FS Jefferson are practically unheard of - and quite valuable if you can find a nice MS example. For example, the PCGS price guide has a 1954-S MS65FS Jefferson valued at $6000.
Take a look at my other hobby ...
