What this coin looks like (obverse, reverse, mint mark location, special features, etc.):
This variety of the 1823 Capped Bust Half Dollar features the "Patched 3" in the date. The broken 3 was repaired with a patch placed in the middle of the "3". This resulted in a blunt punch bump that filled in the center gap on the outside (right side) of the "3" - to connect the two broken parts. The difference between the normal 3 vs broken 3 vs patched 3 vs ugly 3 vs tampered 3 is depicted below in the example comparison image of all 5 major varieties:
