You may be thinking of the 1817/3 half, but the 1806/5 Quarter is nice also. TD

There are quite a few. I have to agree that the 1817/3 Bust half is the most visable along with the 1942/1 dime. However the 1820/19 & 1818/17 bust halves are quite easy to see also. Large cent 1820/19 & Maybe the1839/6. The 1918/7-S quarter is easy to see on high grade specimens.
I remember seeing a foreign coin some years back..........I can't even remember the country, but it was by far the most extreme overdate I have ever seen. If I rember correctly, the coin was not even that old, seems like 70's or 80's.

Technically, the 1844-O half isn't an overdate..... It's a "repunched" date

For the record, the 1805/4 Wide Date half dollar is the most visible US overdate. There are only 31 known, my example is the only one that I have seen posted on this forum:
It is easy to understand why it is rare, the obverse die shattered early in use.

I would say that the 1802 over 1 wide date Bust Dollar would probably be on the list.
On the other end of the scale the 1796 over 5 half dime is best spotted from the reverse.

I am also collecting at least one coin for each Roman emperor from Julius Caesar to ... ?
1802/1 gold $5 and the 1803/2 gold $5. These two $5 gold coins only exist as overdates with no non-overdates known for those years. Both are visible with the naked eye..

Buying top quality Seated Dimes in Gem BU and Proof.
Buying great coins - monster eye appeal only.
I think that the 1844-O Half has a pretty prominent overdate that doesn't need magnification.
Most obvious though would probably be the 42/1 Merc because it's right out there and plain as day.

<< <i>1797 1/1 hands-down, if you want to count it as a overdate. if you call it a repunched date, then i'd agree w/ 1806/5 quarter.

In spite of that I was never able to find one.

1806 over inverted 6.
In my series I think the 1880/79cc is pretty easy to see.
