Just picked this up, 1820/19 Curl Base 2 Capped bust Half Dollar (that's a mouth-full) to add to my very small CBH collection. I've always like varieties like this, but have wondered why did they happen? Were they mistakes? Dies being re-used for the new year? If you know why, let me know.
Quite often the dies for a new year were not ready and so the previous ones had to be re-engraved. Here is a Swedish 1950/1
I have two. The 42/41 Merc is a well known over date. Also have an old damaged Reale that has a very clear over date that I enjoy.
I forgot about this one. The overstrike isn’t the date, but it is the same principle. It is an 1801 large cent with an over struck fraction of 100/000.
Here are some of mine. It’s my understanding that an overdate would happen if there was an unused, unhardened die that the mint could easily “correct” the date on. Once the die has been hardened and used, it takes more effort to overdate the die, so the preference would be to use the die as-is with the previous year’s date. 1818/5: 1818/5: 1824/2: 1825/4/2: 1825/4/2: 1825/4/2:
That looks like a repunched mint mark, not a repunched date. But we'd have to see the whole coin to tell.
