It would not be economical, as the coin's value does not exceed the cost of slabbing.
Actually, the premium can be rather impressive when dealing with die rotations of over 90 degrees. The most popular ones are 180 degrees ("medal...
It's a "straight clip". The blank was punched out from the leading edge or the trailing edge of the coin metal strip. I'm not sure why the...
By "common" I'm referring to this type of error relative to other types of errors. Clash marks are rather common, although examples this strong...
Could be a collapsed blister in the plating, or a collapsed bubble pushed up by subsurface corrosion. However, the image is too small and the...
It's post-strike damage. The puffy letters and numbers are incompatible with a grease strike or any other error.
There is no such thing as an "overlapping rim cud". It's either a rim cud or a full-fledged cud. The first cent presented on this thread...
The 1836 dime shows a retained cud.
This 1830 dime is simply damaged. There are numerous impact depressoins on the obverse which cause the reverse face to bulge out in the same spots.
If the blemish is raised, then it's a cud (die break).
There is no doubt that this is a relatively strong die clash. It's actually a double clash, since the columns of the Memorial are slightly...
It's post-strike damage. The elevated pressure ridges that flank the indentations are a dead giveaway.
It could be struck on a planchet that was improperly annealed. For reasons that are still not clear, excessive or prolonged heating in the...
The first coin shown on this thread is a victim of post-strike damage. Both surfaces were pounded into mush and some metal from the edge was...
It looks like an authentic error to me. The weakly-struck areas on both faces are signs of authenticity, and effects often seen in missing clad...
I agree that the second strike was delivered by a pair of fake dies. The soft, blended overlap is characteristic of such fakes. A genuine...
The "bubbles" might instead be a series of die dents. At any rate, the pattern of exposure of the zinc around the periphery of the coin is...
Without a photo or a more detailed description, it's impossible to diagnose this error or even determine its authenticity. If its diameter is...
The broadstruck half dollar with clip is absolutely genuine. I'd guess its value at somewhere between $100 and $150. A curved clip will...
Chris' study is far from conclusive. The jury is still out on the nature and origin of the "extra leaves". Unless you tuned me out completely,...
Separate names with a comma.
