Dearborn Moderator United States 95630 Posts	Posted 02/25/2023 8:35 pm With MD, the devices will be narrowed and step like (the doubling will be a bit lower) with DDD you will notice that the apparent doubling will always slide towards the rim all the way around a coin. (at the top - towards the rim above, at the bottom - towards the rim below etc.) Collecting since 1972. Learning from then on "Tell me and I forget. Teach me and I remember.

Basically a MD has reduced devices. with step like Doubling. On a DD, the devices are the same size with flow marks that head towards the rims making the devices look like they are Doubled.
