Fresh Find Valued Member United States 138 Posts	Posted 09/28/2023 10:29 am @Chase007 Why is it that the Machine Doubling starts at the bottom and gets thicker on the way up and it's not removing any of the original lettering? And at the bottom it blends in with the lettering not showing it being gouged out.? Edited by Fresh Find 09/28/2023 10:31 am Report this Post to the Staff
Spence Moderator United States 34396 Posts	Posted 09/28/2023 10:40 am @fre, MD typically shows up as shelf-like doubling that serves to reduce the width of the design elements. It looks to me like that is what you have here. However, it doesn't always follow any one specific line associated with a letter and that is why it seems to have unevenly affected the left part of that letter A. Here is a link to the varietyvista page showing that there are no known DDRs for this date/mint--you could look at one of the others to get a better handle on what to be looking for: http://www.varietyvista.com/12%20Ke...Listings.htm "If you climb a good tree, you get a push." -----Ghanaian proverb "The danger we all now face is distinguishing between what is authentic and what is performed." -----King Adz Report this Post to the Staff

Dearborn Moderator United States 94908 Posts	Posted 09/28/2023 1:25 pm well, out of the last 3 images, first one: questionable - but I lean towards MD Second image looks like a DDO on a cent. Third is MD Collecting since 1972. Learning from then on "Tell me and I forget. Teach me and I remember.

Fresh Find Valued Member United States 138 Posts	Posted 09/30/2023 05:08 am The three somewhat random pictures of coins are from wexler's doubled die. The second t and e both have this questionable doubling also The D of United and the complete word state have this questionable doubling Report this Post to the Staff
Fresh Find Valued Member United States 138 Posts	Posted 09/30/2023 05:24 am @John1 Yes I have read the literature on variety Vista wexler's coin help you and Mike Diamonds write up on the topic. What I don't understand is how it has a pivot point and at the bottom of the first t and A they are together at the same height before slowly splitting apart and there is no what I like to call ice cream scoop effect. And the second tea which also displays the questionable doubling seems to be thicker than the first t and the e also displays the questionable doubling Which is similar to this doubling that I pulled from wexler's website I am not saying that wexler's image is what my coin is I'm just saying it displays similar characteristics to the 1970 s 25¢ pr wddr-001 Report this Post to the Staff
