How much is an antique skeleton key worth? Antique skeleton keys typically are priced at $10 or cheaper, while older skeleton keys or more detailed skeleton keys cost as much as $1000.

How do you make an old key look new? Spray a hydrogen peroxide and vinegar solution onto the key.

How can you tell how old a skeleton key is? Age of the Key
A few keys are stamped with a date, but this is uncommon. Most skeleton keys you encounter are from 1940 and before, but some keys are very old. Examine the key to determine whether it appears handmade. If it is not uniform or appears to be hand-worked, it could be an older example.
