Where Can I Sell My Circulated, Error Coins?

Well for starters, the 1985 cent (first image) is not an error - it looks like someone crushed it with some kind of tool. you can see where the rim was deformed and metal rose up around this anomaly.
the second coin (the 1944-S cent) looks interesting, maybe part of a Rim Fin fold over or a weird Cud. need close-ups if it to know better.
the 3rd coin (the 1969 Quarter) is just a common Struck Through Grease and usually does not bring in an increased premium for it. (although there are collectors of this type of 'event)

ebay would be a good start to try to sell your 'error' coins to get a good feel for what the masses want and are looking for.

edit to add:
Oh and Silvio was just sending you a welcome greeting to you to the forum here
(as I should have as well), so here it is:
to CCF!

You can continue to send pictures but list each one on its
own thread as it gets confusing listing more than one at once.

Damage to a coin by alteration, usually leaves the weight normal on the coin. If a coin is dipped into acid, the weight will be reduced in weight. So you might want to copy this weight/tolerance chart?

If a coin is a lamination, the area missing will show a weight reduction. But on the cent above the coin was altered with a vise grip pliers. So this is just coin damage. A lot of damage happens on coins in circulation/or altered in a garage. These will only be face value coins. If you sell of these, you might get flack because they are just coin damage. Some coins are die events. These are from aging dies. So not all that people call errors are ones to buy or sell. They are just normal coins with aging dies/die events. So take you time here to learn what to sell. Errors is a deceptive term. To learn a lot faster, you might ask for opinions here on your own threads. Then you will get an opinion on what you really have, first before selling coins. A quick place to look in the on the top lines of the threads:



Look for this one. I recommend looking the the last page first and then do in reverse. That way you can learn the current information a lot faster. There are 16 pages so far. To read this all would probably take months. So take your time and study on these posts that are addressed their. A lot of information and a lot of images. I'm adding sometimes daily on newer information. So enjoy and grasp the subject fully and then move on. Ask questions as a new thread topic. I'll see them faster that way. Sometimes I may miss questions on the CoopHome files. So always start a new thread and other and I may help you faster that way. A lot of subjects could already be answered on different threads that are already there. So looking forward to you next posts. (A wide variety of information are contained on those links. Coins/images/lighting/editing are also subject covered there.

to the CCF You came to a great site to learn what an error is and is not. Study how coins are made, then you will know if it's posable or not. If you just started out thinking you have found hundreds of errors worth selling on an auction site, hate to tell you you are wrong. I along with I would say most of us here with decades of searching only find 1 or 2 coins worth sending to a high-end auction.

to the CCF

So far we have seen no error coins worth any numismatic premium - and certainly not something a major auction house such as GC, Heritage or Stacks would care to see.

Your aspirations to acquire and sell for profit valuable errors alas has appears to run into the reality that you have collected damaged coins so far.

I'm hoping for you - so continue to post individual threads of the coins and we can help.

Hello and welcome to this forum. Herritage will only accept coins for auction with a very high value. I Think that I saw somewhere that they only accept coins with a minimum value of £5000 pounds in my case because I live in England. I have a genuine error coin which is worth around £2000 but Herritage would not accept it because it didn't meet their high standards. My coin is now with Tennants auctioneers waiting to be sold. Anyway, you need to be carefull when stating coins are errors. 95% of people that think they have errors actually don't, mostly just PMD or altered in some way in a shed. It's likely that out of your 100 error coins many are not. This forum has excellent numismatics and yhey will help you on your learning curve. Be careful not to bombard this forum with error coins as it may annoy some people. Saying that just post one or two every week and read people's feedback to learn.

If it's the same topic, we prefer you continue posting (unlike say Reddit) you can put a new photo in a reply.

If it's a different topic OR a different coin, there's a preference for a new topic, unless the new coin is a DIRECT response to the same topic.

There's a bit of nuance in this as to how direct is DIRECT. "Hey, I found another one where the die break has progressed" is fine in the original topic. I have a BIE "error" from another year is probably OK if the original was about a BIE and somebody replied yep, those are common in the 50s.
