Comets I've Seen (with or without binoculars unless telescope is mentioned; may not include all I've seen, due to lack of record-keeping)
First: either C/1957 P1 (Mrkos; =1957 V) or C/1956 R1 (Arend-Roland; =1957 III) — I remember my dad showing me a comet, and the year was 1957, but I still don't know which comet it was.
C/1996 B2 (Hyakutake) — a great comet
C/1995 O1 (Hale-Bopp) — a great comet
C/1999 S4 (LINEAR) — unexpectedly disintegrated; seen with telescopes; all the others seen with or without small, handheld binoculars

C/2002 C1 (Ikeya-Zhang) — evening comet easy with 10x50 binoculars
C/2002 T7 (LINEAR) — Feb. 2004, just barely visible from a dark site with 8x42 binoculars
