JP324 Valued Member United States 73 Posts	Posted 11/10/2008 10:19 pm Thankyou wheezydog. The set up I use is a dino-lite, photo box and 8 LED's plus a custom base that I made. Report this Post to the Staff

homiegrubbs Valued Member United States 201 Posts	Posted 11/10/2008 10:42 pm I don't think it's an RPM because the mint mark was put on the die starting around 1990. It looks like separation from the copper and zinc due to the hard strike of the die. Bill Report this Post to the Staff
foundinrolls Pillar of the Community United States 3507 Posts	Posted 11/11/2008 12:20 am homiegrubbs is right. It cant be an RPM since mintmarks were no longer punched into the dies by this point. It is Machine Doubling damage. Thanks, Bill Report this Post to the Staff
coppercoins Pillar of the Community United States 7629 Posts	Posted 11/11/2008 10:54 am There's what Bill said along with the fact that the 'doubling' is very flattened and has scrape marks on it where the die and coin slid against one another. That never happens on RPMs. Report this Post to the Staff
Alex Swanson Valued Member United States 74 Posts	Posted 11/11/2008 8:36 pm looks like Machine Doubling to me because the date appears to be doubled as well. Report this Post to the Staff
coppercoins Pillar of the Community United States 7629 Posts	Posted 11/11/2008 9:47 pm Barely visible on the second 9, but I do concur...it is Machine Doubling. BIG HOWEVER... The rule about the date and mintmark doubled together is ALWAYS Machine Doubling ends in 1989. In 1990 the mintmark was in the design that created the die, thus any doubled dies would ALSO double the mintmark. Case in point, 1995D-1DO-003. A true hub doubled die that shows doubling on the mintmark BECAUSE of the doubled die... http://www.coppercoins.com/lincoln/...ie_state=mds Report this Post to the Staff
