@Quintus Arrius If you feel it matches one of the known examples on doubleddie.com or variety vista why wouldn't you post a link to it? If you believe it's a new discover and feel confident in your ability to identify doubled dies, tell us the characteristics you see, such as split serifs/notching, rounding, or thickening and post it. Discussions around those types of posts can be very interesting and help newer collectors However, if you're just taking a wild guess because you think you might see something different and don't bother checking for known examples or can't identify any doubling characteristics, then it's probably a good idea to think the better of it.

In my opinion, the most important thing that this board can do is provide accurate answers. I try to make sure my replies are correct, but sometimes they're not. In this case, I was thinking partial indent but couldn't remember the terminology, so I checked error ref. I didn't take the time to compare the pics to the OP coin so I missed the distorted shape. You pointed out those details and I believe it helped get to a better answer.

Good point. While a partial indent is technically a strike through, the OP coin may not be struck through another planchet. Could be struck through remnants of a die cap which could be thinner and allow for some design transfer and would also explain the irregular shape

I have the error ref site bookmarked. It's very useful for people interested in mint errors. Lots of good stuff there

I see no evidence of die clashing, doubling, or a 1941 date from a Canadian quarter (are you really serious?). What I do see is a coin struck from a worn reverse die. Here is an overlay from http://www.maddieclashes.com/ to help visualize a clash

Partial indent error https://www.error-ref.com/indent-partial/ Nice find

I believe it's a genuine clipped planchet

The date IS NOT punched into individual dies. It is added upstream in the die making process ( I think it was the master die step in 1985, but don't quote me). This means it's not possible for an individual die to be have a number or letter from the wrong punch.

@Keith Dee This is what you need to see on the 1969-S doubled die.

@RWB Are you auditioning your stand up routine to be the entertainment provider at the next ANA banquet?

I recently moved and haven't found a place for my Library, so my references are still in boxes. Unfortunately, RIC V is on of the two I don't have (if I remember correctly, the original Volumes (i, ii, and iii) were last published 70-90 years ago and an update has been in the works for 10-20 years). I think (operative word is think) that the B is the officinae (thractual shop in Cyzicus that minted the coin). They are sometimes denoted by Alpha, Beta, Gamma. Etc.

It looks like split planting that is corroding. When the coin was struck, the metal flow caused the thin copper plating to split, exposing the zinc to the elements. Over time, the zinc has started to corrode. It's not an error. You'll see this on cents, especially from the 80s. It's seen frequently in the date/mm area. BTW: the following sites have extensive listings of RPMs. Your coin won't be there because it isn't an RPM, but they are good sites to bookmark (They are also excellent resources for doubled dies) Www.doubleddie.com Www.varietyvista.com

Looks like this, except yours has a B in the left field RIC 364 Aurelian AE Antoninianus. Cyzicus mint, 274-275 AD. IMP AVRELIANVS AVG, radiate, cuirassed bust right / ORIENS AVG, Sol walking left, holding globe, right hand raised, between two captives, Epsilon in left field. Mintmark XXI. Cohen 154; Sear 11572v. Scroll down until you hit RIC 364 for a pic https://www.wildwinds.com/coins/ric/aurelian/i.html

It's a 1952-D cent that that was damaged, not an error. The date took a hit and that's why it looks distorted. I don't see anything else other than some circulation contact marks and a little environmental damage.

It'snot an error, it's been exposed to something acidic It's impossible to determine the type of acid or the motive. However, I did perform this experiment a number of times while in grad school. HNO3 works really well. Your coin was not struck on a dime planchet. In 1859, dime planchet weighed 2.67 grams, so you're still missing a gram.

Absolutely unneeded. I lose a lot of respect for members who keep pushing political buttons and I wouldn't be surprised if others feel the same way. IMO, posts like this are no better than the trolls. But some people are compelled to get the last word. And on, and on it goes until somebody gets banned. And I hope that happens if this continues

Stop the political ! You should know better than that Kurt. Did anybody ask you what you thought about #45 or #46? NO. Did your comment provide any information about the novelty pieces in the original post? NO. Why did you feel it was necessary to offer your opinion on politicians? At least @Mohawk made an attempt at an apology for going off on political rant. This is why we can't have nice things around here (to paraphrase an admonishment I used to hear often from my mother). Please refrain from the political nonsense so this can be a useful, informative numismatic chat board. If you think a post is political, REPORT IT to the admin. Hopefully, they will quickly take care of it.

Let's knock off the political . The OP didn't ask for opinions about how members felt about this guy. He had what appeared to be a legit question about a novelty piece and was given good info about them. This is a coin forum, not a political forum. Nobody cares how you feel about him(or other politicians for that matter)

But yours has the damage, which wouldn't occur if it was a brockage, but could definitely occur if it was squeezed in a vise.

No, there is other damage on both sides that is consistent with having been squeezed in a vise.

Looks Like Maximianus After a recent move, all my references are boxed waiting for me to find a place to set up the library. Thank goodness for Wildwinds.com RIC vol V 621 Antioch mint Maximianus AE Antoninianus. Antioch mint, ca 293 AD. IMP C M A MAXIMIANVS PF AVG, radiate cuirassed bust right / CONCORDIA MILITVM, Jupiter presents Victory on a globe to Maximianus, H between. Mintmark XXI. Cohen 54.

@Keith Dee The following is a good explanation of dryer coins. There is also an embedded link in that section that is worth clicking. https://www.error-ref.com/dryer-coins/ You'll here the term dryer coin to frequently describe this type of damage, but it can happen anywhere a coin is subject to long term tumbling. BTW: Error-ref is a great site to book mark if you're interested in errors and varieties

They aren't coins, only novelty tokens/medals. Same for Biden, Obama, H.Clinton etc. pieces. IMO, they aren't worth much unless they are bullion, in which case they're worth melt. $65 seems steep, regardless of political affiliation. If you want something like this for your Dad, shop around Some people like this political stuff. I recall seeing Obama novelty tokens during his presidency, and I'm sure you can find Biden items. Hopefully, members will provide the OP with objective information on these political exonumia, and not send it down the path of a political firestorm. If that happens, everybody loses

It was damaged or machined after it left the mint If it can't be explained as coming from the minting process, it can't be an error. When Planchets are struck, the metal expands slightly to fill the collar. The collar can't be beveled or the coin wouldn't eject (and probably wouldn't fit in the first place). Don't spend your time on proving/disproving how the damage occurred. Spend your time developing a plausible explanation of how it could occur during the minting process.

No problem. You had a legitimate question. Keep posting them. Learning this stuff can take time. Look at the links and save the ones you find useful. (the two I posted in my response to Quintas are good). Also, if you're not already doing it, read all the posts. You can learn a lot from other questions as well.
