I have two 1959 d pennies with very distinctive differences in the '5'. Is the penny with the broader 5 an error?
Welcome to Coin Talk. IMO it looks like the first coin with the mushed 5 is worn down from circulation and/or it was made with a very worn die. Always wait for the opinion of more experienced members
Technically, "unique" means "one of a kind" ... the only one. They struck 1,279,760,000 cents at Denver in 1959, so they are the polar opposite of "unique". I'll say that again. They made more than one billion of them. That's billion, with a "b"! But yes, I think I see what you were trying to ask. No, these aren't errors. They look like normal circulated (and harshly cleaned) 1959-D cents to me, so nothing very special, I'm afraid. Aside from the fact that they're sixty years old and from the first year of issue for the Memorial reverse type. Worth just a few cents apiece at best, or just face value to most collectors.
