Some overdates don't really look like a digit underneath as much as a general shape. Often when the old digit is polished away, an irregular depression remains. This one is a good example of that--it's about as common as the normal 1871.
This is not an over date but is a repunched date. The 1 & 7 for sure perhaps the 8 also. The 7 has 4 to 5 hits on it, the last one also repunched .
I'm unsure what you meant by this--so I'll clarify here on the accepted terminology for an overdate: an overdate is struck by a die that was either re-used (or corrected) to reflect the intended date of minting on the coin. For a coin to be attributed as an overdate, markers need to be visible that signify one digit (or many) over another. In the case above, markers for 7/6 are visible. I could argue that other digits are repunched, but it's not critical for a discussion of the 1871/61. One of the countries I specialize in overdates is Sweden. I have many and stand by my attribution. As seen on Krause's online catalogue: not much premium on this variety
A over date here in the U.S. would be like a coin dated 1844 with a 5 being struck over the 4. What you have there is a re punched . That's where they had a die that was used and reworked with another date re punched over top in the die. A example of this would be 1827 /6 US Bust Half another would be an 1820/19 ,&1818/7 Bust half. Let me hop on my puter and I will post clear cut examples .
Well, my coin is actually the same thing as your examples. The die was originally made/dated 1861, and they re-used it in 1871 by correcting the last two digits. This is why in Sweden they would call this "1871--71 på 61" or "71 on 61" as the last two digits were typically corrected on the die. While such a wide date spread may not happen on US coins, for many mints it was common practice in the 19th C to keep and re-use dies over many years. Not to mention we're talking about Sweden here, not US minting practices. So yes, this is an "overdate" too. FYI: it's my understanding, particularly for US coins, that "repunched date" or RPD applies to the same date repunched over another, usually to correct a mistake in placement--such as this 1894/1894 on an Indian Head cent:
A couple more overdates, with wider date spreads than US coins--but still overdates: Peru 1/2 Dinero 1900/1890: Belgium 2c 1919/1914: Nice RPDs you got there! I have repunched dates too, and do understand the distinction. This is a 1893 Indian Head cent RPD. Snow-1 1893/189(s)
My bad KurtS I misunderstood your original post. Long day here..... but I do love varieties over dates as well as repunched . And those are some sweet looking examples you have posted.
You should search Shield Nickels at shows near you as you'll find tons . The fact is there are move varieties not discovered then are already known. I find all sorts of crazy things going on .....best part in xf.-Au.cond. I'm picking these up very cheap too.
Thanks for the tip! I don't have any shield nickels, but understand there's a lot of interesting varieties.
