If this is a die chip on the MM, there appears to be 2, then the odd's are it's a punch issue? Yes? Also, this is a very close match to DDO-002, 2-O-V-CW from K-9, but I'll let you guys make that call. Thanks
So why is it damage instead of a RPM? 1. First note that area is flattened. (Squashed downwards) 2. Note the area in question doesn't resemble a mint mark punch for that area. 3. The whole date area is showing circulation wear. But that area is even flatter. If it were a RPM, it would probably be close to the same height. 4. There is no spread of a second punch. If it were a RPM, they would need to be a spread that is visible in order for it to be a RPM. The mint being larger, doesn't make a RPM. There need to be a spread.
(West) Note each one is showing a spread area. On your coin there is not spread, just a flattening of the normal device.
