Well the hoot of hoots to me is I ordered a bayonet about 1960 (maybe a bit before, I would have to do some math and not sure I want the answer!). I was around 7 at the time.
You could get amazing stuff for 50 cents. My mission was to cut down all the Devils Clubs (may be unique to AK, kind of a broomstick with branches and lots of stickers)
I failed (much to my regret, I ran into them latter on surveying, nasty things, hard to cut with a machete (put your foot on it first) or a chainsaw (whipping around).
Anyway, the Bayo was a random pick out of a bin by someone- lo many years latter my younger brother is cleaning up his garage and wants me to take my bayonet. I tell him to sell it, worth a pretty good chunk now. Nope, its yours, come get it, no idea why I got it.
Turns out to be a WT and the rarest of WWII. Saw a WT with the wrong grips go for $450. A couple in the $900 range. Amazing.
