From memory I had an incomplete set of about 60 cards from Dick Tracy I picked up for around $5-$7.
I had a complete set of 80 of the live-action TMNT movie cards (there was also a cartoon TMNT set around this time) I bought for the same price.
This was where the prices were about a decade ago, but looking on eBay now, some of the prices have taken off. I couldn't find a group of 10 cards for less than $5-7 now. I used to also have RoboCop, that was a good one.
