Let’s post some of our favorite coins that have cuds on them. I know some of us have really interesting pieces to share. I’ll begin with my favorite cud on a cent coin. The coin is listed in The Design Cud as LC-69S-04 and on the cuds-on-coins website as CU-1c-1969S-01. I found one of these in circulation and it’s the coin that got me hooked on error coins. In 1969 my local coin shop offered $8 for what cost me 1-cent. Yep, that offer of 800% profit got my attention and I still have the coin today. Fundamentally, a cud occurs when a die fatigues and affects some portion of a coin [extending to affect the edge of the coin]. The broken die may be the obverse, reverse, or collar die. PCGS defines a cud as “An area of a coin struck by a die that has a complete break across part of its surface. A cud may be either a retained cud, where the faulty piece of the die is still in place, or a full cud, where the piece of the die has fallen away. Retained cuds usually have dentil detail if on the edge, while full cuds do not”. There are several good books describing cuds authored by the late Arnold Margolis, Sam Thurman & Allan Herbert. The website http://cuds-on-coins.com provides further definitions and a plethora of information online. We don’t need to dwell on the technical nuances of die cracks, chips, and cuds in this thread. Let’s just post some cool cud coin photos. Here is a 1991 cent with a large cud on the reverse: Post ‘em if you got ‘em.
Thanks for the coin complement my friend. I've got about a dozen of that particular one. The pesky LC-69S-04 coins always speak to me when I see one for sale. I don't really search for them but they seem to find me.
At the link below is the only coin I have seen with multiple RETAINED CUDS on it . . . very cool! http://www.toughcoins.com/error-0.05-1866-dual-reverse-die-breaks.html
I own many examples of that one cud because it is special to me. I don't know the total number of cuds in my collection. It is probably less than 100. Here is one I posted recently:
Except for my avatar coin, my cud collection is rather pitiful. I do have a couple of retained cuds that I really like, though. Here's a 2007 dime showing a shattered die and a 50% retained cud: The 1940-S one cent has a bunch of cuds on the reverse. I have retained cuds on both the left and right wheat stalk. This is nothing special except for the exceptional condition:
Love the dime . . . I was underbidder on a coin just like it on eBay sometime in the past couple of years.
Sir these are all very neat!!! You should see the 2007 dime a new member just posted what a beauty as yours are: https://www.cointalk.com/threads/2007-p-dime.255026/
I asked for some cool coin photos & you certainly came through with your dime. Here is a dime that I found at a coin show in 2004:
Sam Thurman returned a couple of my coins that he wanted to photograph. In the return package was this quarter as a free gift. The quarter includes a cud on the obverse & a retained cud on the reverse.
I posted this 1948 Brazil 20 centavos a couple years ago. The obverse design is either Mr. Rui Barbosa or Groucho Marx. That is an ongoing debate. Apparently, the obverse die was at one time misaligned to the right far enough that it was hitting/scraping against the collar. This apparently caused the edge of the obverse die to be worn down to the middle of the peripheral lettering. The die was apparently then reseated correctly resulting in the thick rim that extends to the middle of the obverse lettering. Mike Diamond remarked a couple years back that this is a "die attrition error".
I don't know whose brother-in-law supplied the dies for dimes in 2007, but it was some brittle stuff. It seems like we don't see issues on the reverse as often as the obverse. PCGS (Fred Weinberg, I assume) describes this as "Major Shattered Rev Die + 3 Interior retained Cuds". I will defer to them:
I know that our ancient coin & world coin friends have some cud coins but they may not see this crazy error thread. Here is a popular Susan B. Anthony cud:
