davidcyclebackIf a dealer sells 1800s to 1990s baseball, basketball and football, it's reasonable to refer to a price guide. If I asked you what is the value of a 1970s Topps Glossy Bart Starr, you'd look it up on eBay or a price guide-- while the 1970s football card collecor might know the going value off the top of his head.
