My mom had almost collected someones "US States" mini spoons set, when someone told her they were coke spoons she lost her enthusiasm for getting the full set. Some truck stop or something had sold them as a promotional thing, coulda been anything but "mini spoons" were a popular utensil right then.
It was also amusing, as a kid in the 80s, when these things would come out at yard sales and such. Pop up with "how much for this?" and watch someone turn deep pink; or alternately get the last bit of someones antique stash that the rest of their family was unaware of.
