that's a stress fracture within the metal of the penny, sometimes the content of the metal was off a little
and when the press comes down to stamp the coin, instead of stretching the metal it rips it.
don't know if it adds monetary value
I agree some of it looks like stress crack. But IMO the raised parts look to be from a cracked die. No other way for the raised metal areas to get like that other then raising up into the die cracks when its pressed. I agree with Packr on the value aslo. I have some pretty awesome die cracks and they don't seem to get any attention as far as extra value goes. Some people do and have started collecting dies cracks thou and may pay a little extra.
It sure is DJ. 1955 was the year for the well known double die. I have a few poor mans versions. here an example of one I came across that shows the doubling really good.
Wish it was nime Jasper. the only way i will ever own one of those is finding one in the ground. This one was in a PCGS holder graded at AU55. PCGS list the MS 60 at $2300/3200.00. But they also list a 1958 DDO at $40,000.00 for a MS60. man that would be a find wouldn't it.
I know what ya mean tinkb.I would love to own one but unless I find one in the dirt or win at the lottery I guess I'll be happy with my little ole die crack
