So I got this 1965 Kennedy half dollar, I know these are 40% silver, but when I looked at it's edge there is no clad layer.
when I bunch my other 40% halves with this coin in the middle, it just stands out while others have the bands of white and brown layers!
While it's true 40% silver clad halves often have visible layers on the edge, I'm not so sure that's always the case. @SensibleSal66 is offering sensible advice, here. If what my Red Book says is true, then if it's a 90% planchet, it should weigh 12.5 g. If it is a 40% planchet, then a gram less, at 11.5 g.
I have plenty of 65-70 40% halves that have no real visible clad layer. The only way to tell is to weigh it.
The biggest bummer is when you are roll searching halves and see that solid silver edge, only to pull it out and have it be a 40%er.
Oh well. I can see why it caught your eye. I’m still happy with a 40% coin, on the very rare occasions when I can find halves at the bank at all!
Yeah, there's a lot of variation in how 40% edges look. I've seen a few that I would've sworn were 90%, and a few I would've sworn were clad. But the weight difference is unmistakable.
You captured my interest so I went through my '65 Kennedy's and I too have a few that lack the obvious coloration. Great post, thank you.
Coloration on clad edges from 65-70 is nearly invisible since all layers contain silver...80% outer and 21% inner layers...this is normal for these years.
