Vaslin Pillar of the Community United States 914 Posts	Posted 12/12/2007 9:09 pm 1) Mechanical Doubling 2) Unknown, looks post mint 3) Looks like a RPM 1940S-1MM-001 4) Looks mechanical. Overall, you may want to use some acetone and a light brush to clean up some of that gunk. Report this Post to the Staff

chrsb Pillar of the Community United States 936 Posts	Posted 12/12/2007 9:50 pm I have used the acetone brush technique a few times and it works great, especially for RPM's and DDO's. I use my 3 year olds old toothbrush, it is nice and soft and does not leave a mark. I soak the cent for awhile, sometimes a day or so. Report this Post to the Staff

coppercoins Pillar of the Community United States 7629 Posts	Posted 12/12/2007 11:25 pm Goo-gone is far easier to obtain and far cheaper...and it works great. #1 and #4 are both Machine Doubling...it's NOT called "mechanical" doubling. #2 is a die crack that probably resulted in a Cud. #3 is an RPM and does appear to be 1940S-1MM-001. If so, it is definitely also a doubled die. The two are inseparable - they are the same die and had the same doubling from the first moment the die entered service. Report this Post to the Staff
