I'm not sure what you mean "mixed with a penny".
If the coin is made out of copper-nickel like an ordinary dime, but has a cent image struck* on top of the dime image, that's possibly a mint error that happened when a dime accidentally got mixed in with cent blanks and was struck a second time. That's definitely a collectable error but you'd have to take it for in-person appraisal to be sure.
If one side is a cent and the other side is a dime, it's a fake made by joining halves of 2 genuine coins, and has no value other than as a curiosity.
(*) FWIW, coins are said to be struck or minted, rather than "stamped".

The value of a 1989 double stamped penny, also known as a double die error penny, can vary significantly based on its condition and the extent of the error. Generally, such coins can range from a few dollars to several hundred dollars for well-preserved examples.

A penny that is not stamped on either side is considered a coin blank and does not have the legal tender value of a stamped penny, which is one cent. Its value as a collectible or novelty item may vary, but it typically ranges from a few cents to a few dollars, depending on its rarity and condition. However, it does not hold any official monetary value as currency.
The key to valuation is an accurate assessment of the condition of the coin. Some of the "best" double die cents from 1955 can currently go for as much as $1200 to $1300 depending on the all-important condition.
