|Card front (blank back)|
This obscure set from Canadian candy maker William Paterson (cataloged in guides as V89) contains 50 cards and features many all-timers from baseball's first century, including Babe Ruth, Grover Cleveland Alexander, Ty Cobb, and Walter Johnson.
Individual cards rarely appear outside of professional auctions, given the understandable rarity of anything sold a) to kids, b) with candy, c) in a different country, and d) 90 years ago. This is a set best pursued by experienced collectors, since you have to both spend big money and carefully scrutinize each potential purchase for authenticity.
Value: $125 obtained this #5 from eBay. Star players in decent shape cost into the thousands.
Fakes / reprints: Given the set's value, I bet fakes exist--at minimum--for Ruth and Cobb, but possibly the entire set.
