Owen, that's called Machine Doubling. Click the blue link to learn more. It's good to learn fast what is Machine Doubling and what is actual doubling to avoid wasting time on face value coins that usually aren't worth anything to a collector.

That is true, so far I know of 4 types: DDO, DDR, MD ( Machine Doubling), and DDD ( Die Deterioration Doubling).

(on a side note)
We use the letters "MD" quite often, why is it not hot linked yet?
