A dealer whom I know has an 1892 Columbian Exposition half dollar overdate error for sale in MS63 for $1,000. Does anyone have any further information on this coin? I already know that there are only three of them graded in this condition.
I'm not sure if that is possible. That coin was only minted for 2 years, 1892 and 1893. How can it be an overdate if it's the 1892? Over which date?
This thread on another board mentions that there is an 1892/92 overdate listed in the CPG 3rd edition. Another post in that same thread says: "In Q. David Bowers 'Little Editions', 'Review of The Commemorative Coin Market', he mentions that the 1892 has an interesting variety where the '18' and the '92' are different sized numbers. Apparently two sets of different sized punches were used." Maybe that's what this dealer is talking about?
I never knew there was one either. I have 3 of each year so will have to dig them out now and check. I believe the overdate comes about when a master die with a different style or layout of devices is used on a working die that was previously stamped and a repunched date is where just the date in the working die is repunched. I may be wrong though.
A repunched date is the same number while an overdate is two different numbers, it's that simple. In a repunched date they're strengthening an existing number while in an overdate they're changing that number to a different number. Here's what you want to know on these varieties in detail: http://doubleddie.com/58327.html
That is exactly what ive always thought. Until I started studying some overdate coins. I wanted to do a type set, but really didn't want to put together a set of coins that would just be compared to all the other sets collectors put together. I acquired an overdate coin that', I really liked so it just seemed cool to put a type set together using all overdates. I started studying the coins and after a while thought, how can there be an overdate coin with the same date. Then I acquired the one I posted on another thread a couple days ago. I'm not claiming the coin I posted is an overdate, only that while researching what I saw, I found that there are actually coins that are overdates of the same date. That coin was the 1960 large/small 0. The only way those coins were produced was by stamping of the working die with a different master. Doing further research also taught me that most of those type of overdates will show some signs of doubling of the devices somewhere on the coin, giving proof of this. I'm not disputing what is said, just I have begun to look at these types alot different than before.
If it has two different sized dates it would be called an overdate. If striking a working hub re-annealing and striking again to get full details, then all coins would essentially be doubled dies. They are only called such when the subsequent strikes from the same master don't line up. But if they are totally different masters, with slightly different details are they overstruck or doubled?
