Coin and Paper Money Collecting/US coins/flaws


Hello, I have a question about a 1968 dime I found. On the side that has US of A, on it above the O in (of) there is a mark that looks like a pressed in indent. I think it is called a cud mark. On the heads side of the dime, the W, in god we trust is rubbed up against the inside rim and so is the 8 in 1968. I just would like to know if these tiny flaws make this coin less or more valuable, and if so, what do you think it might be worth?
thank you for your time,

With no photo, hard to give you an accurate answer. Could be real error, or a damaged or altered coin. If an error, sounds minor in nature. Very small cuds are not usually valuable unless they appear on Proof coins. Cuds which can be seen by the naked eye are usually worth a small premium over normal value. Altered or damaged coins have no added numismatic value.

Your definition of a cud error does not appear accurate. From A cud is a damaged area resembling a blob on the surface of a coin which is raised above the field a little, and which obliterates the device or inscription where it appears. Cuds are the result of die cracks which have become severe, or from die chips where part of the die surface has become damaged and broken away.

Sometimes you can think you have a real error coin. Here are examples of coins either being altered or damaged.

If you live close to a local shop, they should offer an opinion as to it's value and if it is authentic at no charge. Always try and get at least two opinions and try and deal with PNG dealers if possible. Here's a link to find one in your area:
