Avoid the China Crap. I have quite a few sets, all American. ACE, Hanson, Irwin, Vermont American, these are all inexpensive American sets. If the die stock has a cast center section, it's China. A sometimes cheap way to get an American set is to buy Craftsman which if it's more than 10 years old is Vermont American.
I would expect this set to 50 to 75. It's worth 10x that Amazon crap.
Beware a craftsman set in plastic shrink. That is new and it's China junk.
Metric sets for for more than SAE as there were fewer of them made.
