njguy New Member United States 23 Posts	Posted 09/20/2014 12:51 am The Denver mint mark seems very wide in the Southwest corner and on the western edge it sort of looks like there is another letter under the D, maybe an S? Your thoughts? Thanks for looking! Report this Post to the Staff

small_fortune_ Valued Member United States 77 Posts	Posted 09/20/2014 12:57 am that's an interesting distortion :O probably a grease buildup? Or a die problem. I'm not sure if it's worth much, but it's a cool thing. Nice find. Report this Post to the Staff

njguy New Member United States 23 Posts	Posted 09/20/2014 08:57 am Doing some due diligence I searched the forums here for similar coins and although I didn't find one quite like this there was another coin from 1952 where someone referred the submitter to another website called coppercoins.com to do a die search. I followed the instructions and found a similar mintmark distortion on what was labeled 1953D-1MM-008. There were several other varieties noted as well. While none of these were an exact match to this coin they do demonstrate that errors exist for the mintmark, perhaps this is just a variant of those? Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 09/20/2014 12:04 pm I don't see a match for this one on the resources I've check so far. Makes me wonder if it is PSD though? The loop at the top left side maybe just a fiber creating this. A soaking in some mineral oil should help remove the debris and let us see what is going on with your coin.

njguy New Member United States 23 Posts	Posted 09/22/2014 10:19 am Sounds like a good idea. I'll pick some up today and give it a soak. Having never done that before, what kind of timeframe do you soak a cent in mineral oil for? Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 09/23/2014 11:22 am Sometimes overnight and remove debris carefully with a green thorn. Toothpicks can scratch the fields if you find a piece of sand in the grime. Other times I use a very soft (Worn out) toothbrush with turning the coin and moving in directions patting it dry with a facial tissue. (Do not rub on coin as it may scratch the field if sand is present. Always experiment on a dirty circulated run of the mill coin until you get the procedure down first. Report this Post to the Staff
njguy New Member United States 23 Posts	Posted 10/01/2014 12:38 am Cleaned as instructed with the mineral oil. Nice and gentle. These are the results. Given the other obvious damage to the coin I'm guessing we can't rule out PMD when in comes to the distorted D mintmark? Still though I'd love to know your opinions. Thanks!

coop Bedrock of the Community United States 62064 Posts	Posted 10/01/2014 01:09 am A clear shot of the mint mark would show what is going on in the center. Report this Post to the Staff
njguy New Member United States 23 Posts	Posted 10/01/2014 10:52 am Sadly, I have reached the limits of my ability to get a focused image of the MM using my camera. I hope that at least one of them is good enough. Thank you for your patience and opinions. Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 10/01/2014 12:32 pm Looking at the last images, there appears to be a contact mark on the lower edge of the mint mark that may have distorted the mint mark in that area. I would still keep this one safe for now. Maybe later on you will be able to get better images that area larger. But I'm leaning toward damage causing the look of the lower serif area. I was hoping to see the inside center area of the mint mark. On some RPMs you can see a loop there and wondered if this was the case on your coin? Here is what I was looking for. These are not the same year, but just examples to show what I was looking for on your coin. Not inside of mint mark: https://www.coincommunity.com/forum...-049_LDS.jpg https://www.coincommunity.com/forum...1mm-014m.jpg https://www.coincommunity.com/forum...1mm-015e.jpg https://www.coincommunity.com/forum...1mm-009m.jpg https://www.coincommunity.com/forum...1mm_003m.jpg https://www.coincommunity.com/forum...1mm-021l.jpg https://www.coincommunity.com/forum...1mm-060l.jpg https://www.coincommunity.com/forum...1mm_007m.jpg Seems like if your coin was a RPM, then we might see loops in the center of the mint mark?

njguy New Member United States 23 Posts	Posted 10/02/2014 11:23 am Thank you Coop. I see what you are looking for. I'll try again to get closer using a flatbed scanner since my camera has reached it's limits of macro/digital zoom. Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 10/02/2014 1:35 pm It would probably be better to try a loupe or magnifying glass to take images with your camera through, rather than using a scanner. Scanners can be set for larger pixels, but you need images with light and shadows to show what is raising from the fields. A straight on shot through a scanner will not show this.

njguy New Member United States 23 Posts	Posted 10/02/2014 3:15 pm So I ran the flatbed at 1200 dpi and again at 2400 dpi. Both pictures are enormous and allowed me to see clearly into the D. There is no sign of doubling whatsoever, in fact it didn't look anything like those great photos you posted links to. It simply looks distorted due to some kind of impact damage. Thank you again for your keen eyes and knowledge. How are you with Morgan Vams? I posted a shot of my 1892CC and I think it might be a VAM 11 but haven't gotten many replies on it...think you can take a look? https://goccf.com/t/187591 Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 10/02/2014 4:04 pm I don't have an interest in VAMs. Just not my cup of tea. Report this Post to the Staff
