Hello,

Please take a look at these attached photos and let me know what I have here in terms of possible hub doubling etc.

If it does turn out to be something rare, please let me know what the approximate retail price would be for a coin with this characteristic.

Thanks,
mdpmedia

I know that is not a double die. If anything, it is a RPD. I can't explain away the stuff on the 9, but I can tell you that the stuff on the 0 is PMD. I highly doubt this will turn out to be something valuable.

It is not possible to have a RPD (repunched date) on any US coin after 1909. That is when the mint stopped hand punching dates on dies. I agree that the 0 is PMD but the 9 looks interesting. It's hard to say if it is a DDO or not.
Rest in Peace

That must be a typo.

It's not a typo. This is from John Wexler's site: "When the Lincoln Cent was introduced in 1909, the Mint started placing the last two digits of the date into the master die, rather than punching them into the individual working dies.  For years die variety specialists thought that the last two digits of the date were punched into the master die, however, compelling research by Robert H. Neff has shown that the last two digits were engraved into the master dies and were not hand-punched.  This change effectively eliminated the repunched date error."

I checked on Heritage Coin and many examples of that year showed the fatter 40 in the date. Others showed a date size of the narrow devices. So there mush have been different master dies for that year. But seeing BU examples with the same size confirm to me, this is just normal for this year.

But there "0" looks like contact on the top edge and the "9" looks like ejection damage.

Stated in more general terms, RPDs are not possible on any 20th century coin series.

Gmwavdav, I was mixing up the term with Doubled Die and Repunched mintmark.
Thanks for your information.
