1954 S Lincoln Cent roll: 50 Circulated coins all with a Hooked 9 Variety  in the date 1954.You can see this in the curl in the nine , it has a little hook like shape
This roll and the other error cents were assembled in the 1960's by a man in Sonoma California.The story I got was this man went thru tons of cents  pulling the 1954 San Francisco Mint error coins.I obtained access to a supply of these coins. The coins are all higher grades, and the errors easily seen.I don't think you will find an opportunity to pick up some of these Error coins.Single coins seem to sell well ,so if you have the time, energy, and place to sell these , a person can buy these and resell.Check out my other items!
