When a coin is holed how much of a knockdown in grading is there? Does the size of the hole matter? I'm looking at a coin with a very tiny hole.
In general a hole is likely to destroy a coin's numismatic value. That said, there are many exceptions to that "rule". Location of the hole probably matters more than the size. A relatively large hole that doesn't destroy any legends or design elements will probably have less effect than a smaller hole directly through the head of a bust. Also, the rarer the coin, the less effect on value from a hole. Then, of course, there are actually collectors who seek out such coins. So, as is so often the case in numismatics, the answer to your questions is "It depends."
Thats about what I wanted to hear, the coin I am referring to is an 1800 over date,the hole is maybe 1/32 in. and does not touch the rim or legend. It's a really nice cond. coin and without the hole would be quite pricey, picked it up real cheap.
in general a holed coin is worth about 1/4 to 1/3 of the value of the same coin (in the same condition) without a hole. While hole size matters, it only matters a little and then mostly because of what it destroys on the coin.
