Burger King published 9 sets from 1977 to 1980, mostly team-specific collections like today's 1978 Yankees (full BK set list). This one includes 22 players and an unnumbered checklist, featuring HOFs Catfish Hunter, Goose Gossage, and Reggie Jackson.Topps' bad art to BK's portrait.)
Like other 1978 Burger King issues, only the checklist differs from the Topps design (PhillySportsCards.com has a nice gallery), so people often confuse the two sets. Card number (and pose variation, if any) distinguish them.
Value: Complete sets go for $15-30, depending on condition. Besides the HOFers, semi-stars like Ron Guidry and Willie Randolph cost more. (PhillySportsCards.com ranges from $.15 to $4 for singles.)
Fakes / Reprints: Burger King cards are available on eBay (and elsewhere online), so Yankee fans can probably get them. They're not valuable enough to be worth reprinting or faking.
