This coin took some extended hits on the road and was left for a time in the elements giving it this dirty and yet slightly oxidized natural look. The coin has a value of one cent although some collectors like holding onto coins such as this.
It sure displays its brutal existence for 38 years, but on the plus side, it's not a Zincoln, so it will be around for a long time (if it doesn't get into more trouble ). And, it's holding its value: $.01
Once you understand and see enough instances of road rash the damage will all make sense ... or cents ... if you google "penny cent road rash" you'll see many examples. Of course, since a road (a) has various coarseness of surface; (b) various coarseness of debris; (c) various things running it over; (d) various other environmental impacts, the result upon its removal from that environment can thus vary greatly.
It is only worth the education you received on PMD or post mint damage. Adds absolutely no other value. So it is a spender. Going forward you should know that anything like this is not worth the time to photograph and post because the education value is now used up on this one.
Your question was not stupid. But if you don't understand the answer, let us know so we can clarify. Any damage inflicted on coins once they leave the minting chamber do not add value to the coin. Damaged coins are not errors or varieties. Most mint errors do not add much value either. Varieties can be valuable. Happy hunting!
