I have always been a little sceptical about some of the so-called "proofs" and/or "specimens" of the 1874 series. LCA have sold several F74 proof pennies (I have bought one) and although they are sharply struck with good surfaces, I have never been totally convinced that they were struck as proofs. Interestingly, they offered in September 2012 a "unique" 1874 (no H) 6+G penny for sale, ex-Freeman who described it as proof. The accompanying description was interesting as it exemplified the debates around proof/nonproof pennies of that era. The coin was unsold and I don't recall why I didn't buy it - I guess I wasn't convinced.
