Sometimes I long for the days when baseball cards would come on packaging, not just in it. Many years ago, when a product advertised a free baseball card with every purchase, the cards would actually be part of the box. To get these cards, you would actually have to take a pair of scissors (or something equally sharp) and cut out the card from the box.
For this reason, these cards don't always look the greatest. It's also this reason, that these sets are easier to collect. Some persnickety collectors will not put their grubby little hands on anything that is not mint. These cereal cards are heaped into piles and largely forgotten. Sometimes, you can find bulk lots of these cards on eBay and other auction sites. If the cards have seen better days, you can find fantastic deals.
The 1962 Post set is fairly easy to collect. There are 200 different cards and eight variations. The variations are as diverse as blue lines or minor corrections, such as spelling. Presently, cards like the 1962 Post are getting a second look from collectors.
You can amass the bulk of the set very quickly and cheaply if you are persistent. Since there are cards of Mickey Mantle (which is one of the variations), Sandy Koufax and Roberto Clemente (another variation), completing the set may prove costly, unless you find a real bargain.
Sets like this are fun to collect and can enhance your collection instantly.
