OED gives two (2) major sp. variants: tsatske, tchotchke

[a. Yiddish, f. Slavonic (cf. Russ. tsatska).]
A trinket or gewgaw; transf., a pretty girl. Also "tsatskeleh [Yiddish -le dim. suff.], an affectionate diminutive of tsatske.

the first citation is from 1964(!) and this from:
1968 L. Rosten Joys of Yiddish 408 Tsatske and tchotchke are used interchangeably.+ At one time+West End Avenue in New York had an inordinately high proportion of tchotchkies.

so we're left to wonder if he meant gewgaws or pretty girls...
