It depends on the type of coin the date and denomination on were the mint mark is located
Please post a new question with the coin's denomination. Also look for a small letter like an A, D, G, etc. somewhere on the coin. That's the mint mark and could be important to its value.
You should look for its condition, its age, what denomination it is, and if it's a US or German coin, whether it has a mint mark letter..
Which coin? Post a new question and include the denomination and date.
