Here's a 1993 Roservelt dime with strange doubling on the mintmark.I no this is not an RPM, because the mint started putting the mintnark on the die in 1990, I think it was that year.The doubling on the mint mark is rounded and raised the only conclusion I came to possible die deterioation doubling ,but than again there are no other indications of that any were else on the coin. When there is die detrioration usually you would notice an orange peel effect on the fields or near the doubling no indication of that. I never heard of just a double die mint mark could it be possible maybe you never Know in the crazy world of errors. What do you think feedback please I took different angles to try and make it easier to see I tried to take the best pictures I can you may not notice the roundness on the minmark but it;s there. Jazzcoins Joe:whistle::whistle:
Joe, I seem to see some strike doubling on the date also, in the same direction, but not as strong as the mm. If so then the mintmark is probably machine also. Can you sometime take a photo with the focus on the date if there is any. Jim
It looks to me like it's a clear case of reduction lathe doubling. Had you going there, didn't I? How do you know that's not just how that mint mark looks? Do you have another 1993-P dime? I'd make sure of that, first. If it still looks funny, how do you know they didn't rework the hub or die? Agreed there's no way that's die deterioration doubling, though. Just don't look like it. OK, doesn't. FWIW, Joe...
This one has baffled me for a long time, i usually hit it on the head when it comes to detecting doubling. I know you no the feelling when you try and figure these errors out like your 1930cent/I looked at many 93 dimes no other mint mark looks like this. I did rule out strike doubling , because these images are raised and rounded not shelf like in appearence, The only possible one is die fatigie, but there are no signs of this on the fields and other elements on the coin like i said before . I know for a fact that die deterioration doubling can appear to look very similar like a double die but they appear to be mushy like, and some of the experts have trouble distigushing between the both of them sometimes. I have seen some examples of this were the images are raised with that kind of doubling to an extreme. I will crack this one yet.:headbang: and I don't mean my head either. OH by the way eddie good posiblity when you said rework the hub or die I'm not to sure with reduction lathe doubling through Jazzcoins Joe Thanks for the feedback my friends.:whistle::whistle:
90's Roosey's as I do collect Dimes. I think *Eddiespin has it right"reduction lathe doubling"Ken Potter told me the same thing about a 1993-P I e-mail him picture of and you 93 looks like the one I e-mail Ken
Hi Jello Do you still have that dime, could you try and post it? I"m kind of curious , because I went through rolls of them and didn't find anything like it ,not that there are any in exsistence. just a curious mind HOW ARE YOU DOING JELLO Jazzcoins Joe:whistle:
Jello, that's interesting. Especially from the point of view of somebody who collects these and inquired on one. All I know is this reduction lathe doubling is pretty common on Lincoln cents, even on the newer ones, and, it shows up, principally, as a faint, secondary image, just off the bridge of the nose and around the tip (other places, too), and, you need a 10X to really see it, and, it's just something that happens as they go through the reduction steps. But, that's very interesting, how you're saying it shows up on dimes. Joe, I just thought I'd make sure you didn't just find this dime in "pocket change," and it's the only example you're looking at. Other than that, you know I know the frustration. Don't know what else to say, pal, except I think I'm getting closer to investing in one of those microscopes, too...so be forewarned, CoinTalk...watch out! Good luck, though, and I hope you crack it. The mystery, lol!
encil: Thank you my friend for posting that very interesting specimen. I have to say yours is die deterioration doubling ,if you look at the fields near the date you see the die fatigie orange peel effect(.Dead giveaway) I don't have that on my coin no signs of die fatigie ,and your mint mark is mushy in appearence, also yours is a 2007 ,and mine.is a 1993 pretty big cap. I have rounded images and raised images that's why it baffles me so much. How you doing Jello? Jazzcoins Joe:whistle:
My photos Your right Joe but this one is worn dies here the Obverse & rev photo this a reused die and a 2006 satin die. and that were the lathe doubling is started from the mints take used dies. on this coin it was 2006 satin finish and make it in to a bushiness strike coin. so what I am saying your coin like this was a die that had been retooled.your coin is most likely a retooled 1992
