Look at the Wexler listings for repunched mintmarks. You can find them online at the CONECA website. A good rule of thumb is that if the "doubling" only affects the mintmark it is NOT a double die. If some of the words are doubled it might be doubled but you have to check for machine doubling. Like any variety some are rarer and more valuable than others and they are always easier to spot on higher grade coins.
Sully's right. They're impressions of the same depth sitting next to each other, just ajar from one another.
Show me. There are literally thousands of proven doubled dies that show just the opposite of what you and he are stating as fact. Besides we are discussing a Mint mark and no one but you and he have brought up anything to do with die doubling.
Actually Chris, in the lower left corner of the pic, looks like a tray of squat, with some jack mixed in!
How can you explain the raised circle on those objects? Those look like dies, not letter punches. Keep squattin'! Chris
Looks like I started something lol But Seriously, from all the 1999 I have seen the “distressed hub” happens everywhere on the coin but not in this one.
It looks like RPM with die deterioration MD, but you guys say that hand punching stopped in '90s. Leaves us with the repunched hub? Repunched hub to produce more working dies? Then die deterioration from overuse anyway? Then the condition of the coin...seen some miles. Spark
If by "he" you mean me, Iv'e never brought it up as a doubled die. I actually thought it wasn't a DD but wasn't sure so i asked if it was machine doubling instead. I questioned the explanation of why it was a "machine doubling" since it pivoted.
Looks like MD to me. At least I hope it is because I have tossed a ton of 90's coins, both Philly and Denver, that have MM like this.
In those cois, do you recall if the MD was localized or in several locations? In this coin i only see it on the mint mark.
