The on-line forum www.error-coins.com was hacked out of existence some time in the last two days. This forum may be just as vulnerable, as I...
The appearance is so crude that it's hard to believe that it's retooling. No competent engraver would allow such poor workmanship to enter...
Splitting of the copper plating next to the D-mintmark is rather common. It is not an RPM.
I sometimes happens that coins are squished together in mint machinery after the strike. Such coins can be found in mint-sewn bags. But it's...
No repair was done. It's just die deterioration.
I suspect these are genuine cents that were altered outside the mint. Perhaps they were cleaned afterward.
Sounds like you have a minor misalignment of the obverse die and, perhaps, an unrelated minor filled die error. The weak 5 could also be caused...
Probably a case of mint discoloration. This is sometimes accompanied by closely spaced parallel lines, streaks, or striations. The cause of both...
It looks like post-strike damage in both cases. The incuse letter impressions represent some kind of "squeeze job". The other coin shows no...
It doesn't look like any kind of strike-through I've come across. I'd vote for post-strike damage.
If its weight and diameter is normal, then it's almost certainly plated. Or perhaps it was dipped in mercury.
If it's a genuine rotated die error, then it's worth several hundred dollars, even if it's lightly circulated.
From here it looks like an authentic case of incomplete copper plating.
Sounds like a filled die error. These are quite common.
Looks like a D over tilted D repunched mintmark variety. Nine RPM's are listed for 1971-D cents in the CONECA variety master listings...
It could be one of several things. 1) A lamination flake that's lifting up. 2) A blanking burr ("rolling fold"). 3) A retained cud. 4) A rim...
Could be damage. Could also be a lamination error. In other words, you may be looking at a flake that's starting to lift up.
True, it could be a "brass plated" cent. These are thought to arise from zinc contaminating the copper plating solution. Copper + zinc = brass....
That's not correct. A die clash produces letters that are incuse and mirror-image. Clash marks are generally confined to the field and the...
Color means nothing. Given the right chemical environment, a cent can turn almost any color imaginable. It could also be plated.
