EML Coin Collector Valued Member United States 193 Posts	Posted 02/13/2025 09:34 am ==Chase007== Now if you could do a side by side of MD with a DDO then it would be easier to see the difference. Sounds like a DDO would be having 2 raised areas of the same letter next to each other to varying degrees? Marlies Report this Post to the Staff
