Is it possible for a 1993 quarter to be heavily worn, to where the lettering looks to be a ddo?? The reverse looks just worn, but the obverse looks to be doubling. I will try and get some pics up tomorrow as Im at work right now.
Don't bother with the photos! The answer is "No. unless it was a doubled die in the first place." Chris
I'm always leary of doubling in photos when the light source is 180 degrees from the "doubling." Shadows tend to "create" the appearance of doubling in photos. So, there is doubled die, mechanical doubling and photographic doubling. That is in addition to corrosion confusion and nefarious post mint doubling.
It looks like what you have is die deterioration doubling, also called die fatigue doubling. As the die (not the coin) wears, parts of the design, usually closer to the edge of the die, can start to get a blurry, doubled look to them.
