SPP-Ottawa Moderator Canada 10456 Posts	Posted 01/19/2023 7:30 pm Post mint damage to my eye. The evidence otherwise contradicts itself. The coin is no longer round, which means the collar die was not engaged. The Rim Fin however is a function of metal pushed up against the collar die.

SPP-Ottawa Moderator Canada 10456 Posts	Posted 01/21/2023 9:41 pm Partial brockage of what, exactly?

robmck1967 Pillar of the Community Canada 870 Posts	Posted 01/21/2023 10:49 pm Mike Diamond's comment: This is a very small, aligned partial brockage. In other words, the brockage is aligned with the die-struck details on the opposite face. Such brockages can be produced by an elliptical clip error, elliptical strike clip, or off-center (partial) die cap. The absence of horizontal lipping lowers the odds that it's from a die cap. The absence of an impression of a rounded shoulder reduces the odds that it's from an elliptical strike clip. Therefore, the most probable explanation is that it was generated by a small, elliptical piece of coin metal (probably an elliptical clip planchet) that settled against the striking chamber. After it was struck, this small elliptical demi-coin stuck to the hammer (reverse) die and was struck into the planchet represented by your coin. Report this Post to the Staff
SPP-Ottawa Moderator Canada 10456 Posts	Posted 01/22/2023 12:35 pm Do you not find it odd, that the "brockage" design elements line up perfectly with what the design would be on a normally struck coin? Secondly, the 'brockage' rim thickness is twice as large, but the denticles are not enlarged. Lastly, the depth of the indent is very shallow; much less than any strike-through clip element I have seen on 1-cent coins. As much as I respect Mike's research and work, I don't find his interpretation plausible with this coin. You would have an easier time convincing me it was double struck, with the second strike through an overlapping thin planchet, or a die cap fragment.

Yes! That is why I bought it. I couldn't see anything else that pointed to it being PMD. I like good mystery, don't you? Would you like to examine it in hand? Report this Post to the Staff
