1969-S nickel on dime planchet -- a puzzle
- Here is a 1969-S nickel struck on a dime planchet:
Nothing too unusual about that. There are quite a few 1968-S and
1969-S nickels on dime planchets known.
What's curious is that these are all purported to be struck on proof
dime planchets. The only dimes San Francisco was striking at this
time were proofs.
However, if you look at the weakly struck areas on this coin, you'll
see the small nicks and dings that are typical of a business strike
planchet. Proof planchets are supposed to be highly polished.
So what was an ordinary dime planchet doing at the San Francisco
mint? Did they perhaps use some for striking proofs? Were ordinary
planchets produced elsewhere and then polished at the SF mint? Did
this one then escape this final step and end up in a nickel hopper?
Lots of questions, lots of possibilities.
No longer can one assume that all these nickels, or for that matter
if ANY of these nickels were struck on proof dime planchets.
- Excellent detective work, Lindy. I see that the 1969 1/10 balboa
uses the same planchet as our dimes. And nearly 1.4 million of those
were struck in that year. Raises an interesting question of how
you'd classify this error type. It's both a domestic and a foreign
