I recall this being discussed once a few months or so ago, but I think it bears repeating.....

The minting of the JFK general circulation 40% halves are (pretty much) bell shaped:

'65 - 65.9M
'66 - 109.0M
'67 - 295.0M
'68D - 247.0M
'69D - 129.9M
'70D - 2.2M


Though I haven't found a 70D yet, in the four months since I've gotten back into CRHing, all my other 40%er JFK halve finds have pretty much lined up with the percentages they were minted (found more '67 followed by 68D, 69D, 66 & 65).

Interesting.

Anyone else with similar results ?

I'd say that's pretty accurate as far as my finds as well. '67 & '68 are definitely most common, and I've not found a '70 yet. '65s were pretty uncommon for me as well, but in one roll I pulled out 4 of them, which was a surprise.

My finds follow just like yours, 1967,1968 and 1969 are the majority. The 1965 is found the least and I use to wonder why. lol I've already found 2 of the 1970 halves.

My numbers here are in line with everybody's. Still looking for th 1970 myself.
Prob. the most surprised was finding a 1976-s silver in fine shape.

Last night I decided to put all my halves into rolls by year minted. So I sorted them out in five rows. The length of the rows matched almost exactly the mintage figuers above, except I had a bit more 68's than 67's
