Collecting sports cards used to be a popular thing among children a few decades ago. Almost any kid could tell you the batting average, number of assists, number of yards rushed, and all of the other stats of their favorite sports players all due to these collector’s sports cards. Though sport card collecting is still somewhat a hobby nowadays, less and less people are doing it, and major card manufacturers are not printing as much as they used to. Though this is a sad prospect for sports card enthusiasts, it is also an amazing opportunity. The scarcity of cards has made them more and more valuable, and now, if you have old sports cards of big-time players from a generation or more ago, you could have a real asset on your hands.
