Checking change would be a lot more fun if I understood what I was looking for or at .... but you gotta start somewhere..LOL
If you want to get a “handle” on doubled dies, I would recommend exploring these two web sites. http://www.varietyvista.com/Doubled Dies.htm http://www.doubleddie.com/1801.html It will give you a basic understand but always remember “A little knowledge is sometimes a dangerous thing!”
I'd say MD . Still fun to look at . What you want to see is a more rounded doubling , if it's flat like a stair it usually always MD .
Thank you so much for the web site , I actually have the 2014 Lincoln error cent (shield die chip and chip on forehead), about 50 or 60 of them... got 2 rolls of brand new perfectly shinny rolls, now I feel bad for touching them bare handed.. Now I have to look at the rest again to look for other errors...LOL, LOOK OUT now it's getting REAL..... .LOL
Glad the links worked out for you. I know it seems like “dry reading” sometimes but there is a lot of good information from those two sources. Dr. Wiles (Variety Vista) and Wexler are like night and day but they are probably the two best in the field of studing doubled dies.
From the home page of Variety Vista, James Wiles has a few ebooks for sale. For the beginner or even intermediate collector getting into die varieties, Wiles’ book “WHAT ARE DIE VARIETIES?” is well worth the investment. As far as loupes go…. according to Dr. Wiles, if the variety can not be seen with a 10X loupe then it is probably too minor to list (I myself like the little Bausch & Lomb 14X Hastings Triplet for having the doubling jump out at you).
Just a thought, you do now know to look for or check for die markers right? It is covered in the sites mentioned; when you think you have found a match for a ddo or ddr, you can check for the markers. When I can't find the markers I post it here for the experts here to let me know, learn
read read and read again---I agree, keep looking at the posts here--tons of info--that doesn't cost tons of money----and plenty of the people that post here, not me of course, have written books about doubling issues---much free knowledge here--
