Hey guys, Found this nice looking state quarter, except for the fact that it looks like it's missing a layer off of it! Can anyone shed some light on what this is? Thanks, Jason
I've seen this on alot of state quarters and im pretty sure its caused because the coin was struck through grease.
Yes, it is a strikethrough but it looks like a build-up of compacted grease and debris fell off the die onto the incoming planchet. After being struck into the surface of the planchet, it fell away. Chris
i'm not sure if this is true or not, but when i started seeing this type of "struck thru" on new coinage, mostly quarters and nickels, i tried to research it and found a site which explained it, dont ask where cuz i haven't found it again, the site stated that new dies come wrapped in a very tight and thin form of plastic and when the workers peel it off the dies pieces sometimes get left on the dies which causes this type of strike thru, it sounded plausible, as i've seen this on many new nickels and quarters while roll searching, but dont know for sure if its true...
Be very glad that you can't find that site again. I also hope that no one else finds it. I call them as I see them, and I call that story BS.
We had a very lengthy discussion about my quarter like that last feb or march. IDK that anyone ever had a correct but someone said it was because they used a special die set die or something I think that was no longer needed and refinished and that is why we were getting the ghost image. Sorry may be wrong or my wife tells me I am a lot.
I have to ask this question. This is a question that not even the major grading companies can answer, this is why they're not using the term Grease.filled die and switching to debris filled die. It's quite obvious a lot of members on this site. Do not like change. It is quite obvious and logical at the time someone came up with the term Grease filled die it was probably appropriate and correct 100 years ago. 2017 Grease filled die is definitely still being used but it is totally not accurate. The production of coinage way back when, has changed considerably up to today's production standards.. We have to face the facts and adjust the terminology to suit the production of today's coinage, changes slowly taken place with in NUMISMATIC. Unfortunately on CT a few members pride themselves on being correct in their terminology. In this case they need to come into the 20th century with their terminology. Discuss this quite in-depth with Mr. Moffat, which is a master technician concerning minting equipment, and is also an instructor whose teaches operational procedures with these presses. It is determined there are so many variances in production debris it's hard to determine sometimes what causes the errors. You use the term struck through Grease. Question what kind of Grease was it struck through?. https://www.cointalk.com/threads/grease-filled-coin.293970/
It has always been understood that the term grease filled die involved grease/oil, (whatever you wish to call it) and debris. I only know of one person on all the different coin forums that claimed there was no grease/oil, (whatever) involved because it was no longer used in the minting process. It's a dead issue that no one gives a crap/debris about what term is used. It's not just CT, it's all the coin forums. No one cares.
ldhair Maybe I'm reading different threads and post, even on the other coin sites. I have found the opposite of your statement. Read one of my first post on coin talk. Snow on the roof. I believe in seven or eight pages of how my improper terminology was not acceptable. Double die Acceptable term?.
ldhair And please if you gonna say I'm the only person, at least get my statement right. I still state there is no grease on the production line. I was informed by a master technician there Is a light lubricating coating applied to the rim of the coin so it would not Get stuck in the collar.
Well I'll be darn. There are still lubricants being used in the minting process. Who would of thought.
