Yup. Bubble that got shifted over. Just moved it with a toothpick. Bummer! Fred, can you comment on this from a previous thread? I know what I would like it to be.
Can't tell much from that one photo above. Probably the common ejection or mechanical doubling. A better than-average example, but not a DDO.
I have a hard enough time seeing on my monitor. Besides I simply refuse to give in on the whole phone thing. Only use when I absolutely have to.
I believe you will find that the category of machine or mechanical doubling is also known as strike, ejection, shelf or shift doubling, or almost anything other than true Doubled Die. Jim
Do they all create a shelf like doubling? This one stops at the neck line, shifts to the right and is rounded. This picture shows a little more detail of pattern lines. Thank you.
