1793 Seated Half Penny I found when i was a kid

When i was a kid, my dad owned this building which housed a bank in the 1930s. We couldn't get into the vault for several years as nobody had the combination. When my dad found the combination, we went in and i found boxes of coins which had been drilled or ruined in some way. This was the oldest one. i still have a bunch of them somewhere - lots of coins from 1810-1850 - all w/ holes or something. Am i correct that this is a 'seated half-penny'? i'm not sure which category this falls under.
