Cool.

Looks like striking pressure even and why I am leaning toward a type of die installation issue, and maybe a combination of a couple things.

I do enjoy the mystery, always learn something new.

My camera is 20+. My scope is 18.
I have a slightly used 3 MP scope camera if someone wants it.

I missed something somewhere.
Are the denticles part of the collar or part of the hammer & anvil dies?
I guess I never thought it was anything other than a device on the hammer & anvil die.

The denticles are device, but if the collar is missing it would be mishappen due to the metal extending outwards.

I think Daniel is on to the correct path with improper alignment/pressure. Just can't figure out how central is good strike, but outer is not. Coin is not visibly distended. No step or cracks on edge.

Rick Snow suggested it may be a Type 1 planchet. He doesn't have it in hand. So, hard call and without extracting it, I cannot weigh it. But, color is a bit more like CuNi.

Waiting on reply from Mike Diamond.

My take is that the collar die wasn't flush on the anvil die so the coin was struck normal on one side and not on other other. Of course that would be a mint error and doesn't add to the variety status but a good find either way.

I'm really messing up terms on this one. A Type 1 planchet is before the edge is upset or milled. So, the rim forms differently when struck.

Yes, it is a blank. Missed the upsetting mill process.

Here's Mike Diamond's response:
"I'll take your word that it's not broadstruck. Missing denticles in a coin struck in-collar can have any number of causes: die deterioration (unlikely in this case), peripheral accumulations of "grease"(also unlikely), a slightly weak strike, a slightly thin planchet, inadequate upset of the planchet, or excessive convexity of one or both die faces (a design flaw). More than one of these factors can be at work simultaneously. In this case I cannot identify a particular cause. Specific etiology aside, missing denticles are not that uncommon.

Best regards,

Mike Diamond"

Put that with Rick Snow's response, we have a commonality on the planchet.

Put it with Daniel's response, we have commonality on strike pressure and a combination of errors.

So, in the end... It's a common error, still possibly a broadstrike, that I've never seen.
