While rarity will still effect value, fingerprints WILL diminish a coin's numismatic value. That is why as a general recommendation, cotton gloves are advised when handling unblemished coins. They are inexpensive and available wherever hobby supplies are sold.
You mentioned a 1983 cent, but showed us a 1991 coin. The coin pictured is in rough shape for sure, because of fingerprints.
Searching for--and finding--a legit '83 doubled die ( DDO and/or DDR) will be a chore. Plan on looking through hundreds and hundreds of thousands of cents--and more; high volume searching is key. You could find one next Tuesday, or 25 years from now. I've been rummaging through cent rolls over several decades and have yet to find one.
