Collar Clash

Post by SilverToken » Thu Aug 11, 2022 2:26 am

Is this a collar clash?

It is approximately from 5:00 to 10:00 and follows the rough diameter of a Morgan. The denticles crush deeper towards the center.

Thanks in advance

I don't see a collar clash on that coin.

This is collar clashing (1921-P VAM 3CA2):

When in doubt... don't.

OK

Then is it just considered a clash on the denticles, crushing them 1/2 way down?

Not a clash at all. A clash is when dies hit each other and cause subsequent coins to show the after-effects. Did you happen to catch the doubled stars?

Then what is it called when the denticles are called when they are mashed 1/2 way in a semicircular fashion?

I recognized the double stars, but that is only part of my investigation....

This is found on the 1896 4a, not the 4. I was seeking the correct term, without calling it correct term.

I believe now that it is a denticle clash, just not noted on the VAM, like the die crack above the AT in states

Imo, that's an error due to ejection impact or die slide when the coin was ejected right after struck.

Would that ejection impact account for all of my 96 Vam 4a's and the image posted on Vamworld having the exact subsequent crushed denticles?

FYI the 96 Vam 4 does not have this feature

I don't know how many times the mint worker do adjustment on the press machine. But with an average of 200k coins struck per die pair, the answer is yes.

Re: Collar Clash -Correction- Solved

Post by SilverToken » Mon Aug 29, 2022 7:50 pm

PER Vampicker- this is not ejection impact (or as Vampicker referred to as ejection doubling) but “Strike Doubling”. So anyone who noted this, please correct any adjustments you may have done in your references since this last post.
