Can I believe in this one 1983 DDR ? Cherry picked this one out of a role of 50 from the local bank..
There are two for the year, which do you think it is? http://varietyvista.com/01b LC Doubled Dies Vol 2/1983PDDR001.htm http://varietyvista.com/01b LC Doubled Dies Vol 2/1983PDDR002.htm
What is the best way to clean penny's to get the black crud between the dates and lettering off so that you can notice more of the stuff. I have been washing some if I can't read the date with the vinegar salt mix but some say that is not the best because it basically acid washes them. Is there a better way? Warm soapy water and a toothbrush or anything else?
Olive oil, soak it for month or so. microfiber pat, will not affect the patina, acid damages the coin, and collectors can see that! unless you are wishing to keep forever, i wouldnt go the acid rout.
Good conclusion, I think it is what Treashunt says, MD or mechanical doubling,. It doesn't look like either Doubled Die posted above.
http://doubleddie.com/828823.html add 10 more and a common working hub "doubled die". I can't see enough from your images to consider trying to match it to any of them, although it is likely WWHO-001. I don't see it being either of the two at Variety Vista.
I don't believe his pictures are good enough to actually determine MD, which the poor pictures suggest it most likely isn't, or that it is WWHO, which the poor pictures suggest are more likely. I'm not going to say why I don't think it is MD other than you may not actually be looking and the people that continually post poor pix seemed to have possibly trained several.
WWho-001 is a doubled working hub obverse, WDDO-002 Thru WDDO-010 are all obverse. These don't fit the OP's question. I did see that Wexler has a third DDR in his list, but it doesn't fit that one either.
Reasonably clever catch and it probably is MD. Too bad about the marginal pix. Good thing I'm not on the payroll or I'd have to be drafting arguments why I'm right and why any board members objecting to my antics should be terminated after a tarring and feathering. ;-)
Gotta make sure that the acetone doesn't have any extra stuff like bitterant so people don't drink it.
