Rapecoin sucked pretty bad as well as its claim to be helping awareness for "rap victims" (not a typo). Shibecoin was an obvious rip-off of Dogecoin.
Lol. There's a lot.

Strangely, I get a "This Connection is Untrusted" error and the version without https:// doesn't seem to work. Google's cached version works though although the fonts are rather small. Anyway, I didn't realize there were so many coins... Pyongyangcoin? Mental Health Awareness Coin? (although I guess that one was for a justifiable cause.)
