My first trip to Las Vegas was in 1979, but I didn't start keeping some chips until 1982 or 3 or so. I'd pocket a few chips from winning bets to take home to make sure I had to go back the Las Vegas to play them for luck. Did that for several years. First chips I kept and didn't play next trip were Horseshoe $1's and .25's from Crap Table runs. Poor choice of chips to keep! Why didn't I keep any of the Nob Hill 5's I had in hand. Always stoped there to play Craps tool!
