General discussion board about VAMs, but no buy/sell offers
I would like to add that it is more likely that it is NOT that the coin is still in contact with the dies while ejecting, but more likely that the dies are getting "sloppy" or "loose" and as the dies are retracting they are still in contact with the coin and they retract with a twist, or shake, or shift, etc. That will cause the stair stepping you see in many coins that are machine doubled...my 2c.vamsterdam wrote: ↑Mon Oct 28, 2019 5:12 pmMachine doubling damage steals from the design to create a “doubled image.” The coin is still in contact with the dies while being ejected. However, in the case of die deterioration doubling, as has been mentioned, the dies become damaged due to wear and tear, and repeated attempts to polish the dies. Many of the doubled ears fall under this category and should never have been listed. Longacre doubling is another story and rarely happens on Morgan’s, probably due the size of the dies involved. It is often seen on Indian cents, 2c, 3c, $1 gold, $3 gold.
