you tell me what ya think

I've seen that before. Rather than saying machine doubling, I would say ejection doubling. The marking usually only affect certain areas and the rest is normal. The distortion is cause by the ejection of the coin from the collar. Probably the U is the only thing affected?


The doubling is visible, but not disorted like machine doubling which affect several areas of the coins. The ejection doubling seems to only affect the contact points during the removal of the coins from the striking process. On the two examples posted the only area affected was what was shown. If it were a doubled die several areas would be affected as the hubbing creat more doubling than just one point. The different classes of doubled dies indicate that several different doubled dies can come from the hubbing being different creating them in different ways. Hope this helps.
