DOWHAT : And if it is rolled thin planchet from rolled thin stock, is that not considered an "error" on behalf of the mint?
Please explain these two very confusing conclusions.
The rolls in 1968 was 1100 Ft. long for halves. The thin roll not "planchet" could be from core roll or from the cladding rolling. Those are partial and in general could be find in the begin or end of the rolls. Those are not errors. Happened on all denominations and all the years. This anomalies is frequent as the floating roof on Cents.
I was and consult the year foreign coins struck and no one meet the closers parameters.
Now I will put here the specs as per Mint and the 1965 Law:
Quote:
3-layer composite coin. Outer cladding 800 parts
silver, 200 parts copper
bonded to a core approximately 209 parts silver and 791 parts copper.
Thickness on edge = 2.18 mm, Diameter = 30.61, Weight = 11.500,
Min, weight = 11.100 and Max. weight = 11.900, Reeds = 150
Those was the Halves 1965 till inclusive 1970. 1968 do not has P or S and only D (Denver)
Hope this will help everyone.
