If the coin was in better condition you would say it was from a grease filled, or debris filled die. In this state, that could be one explanation. The other could be damage. Always show the reverse. I'd keep it just as a curiosity, but I doubt it has very much value.
Looks like a filled die. I have a couple with a filled 3 and 4 but none with 2 digits missing. From my observations in over 45 years of collecting, it seems that the steel cents have more filled digits than the regular copper cents. Cool coin, but in that condition, any premium would only be a buck or 2. Even at that value, it's definitely a keeper, IMO
