About $1.5 dollars, according to price guides.
If you are holding one it is real. Star was a short lived baseball card company that produced cards around 1989, and 1990. Not able to compete with baseball card giants like Topps, Donruss, and Upper Deck they went out of business. They are real, and will sell at a real price.
In looking at Beckett Price guides for 1991 Robin Ventura cards, you will see prices range from $0.10-.50. Now, sellability is an issue, as the print runs associated with cards from this time period would have way more available cards for sale than there are buyers.
Recently in an eBay auction, I came across Randy Johnson Donruss Rookies Mariners on offer for $299.99. If you are looking for a specific card, you may check the eBay auction listing and also visit beckett.com and check the baseball card online price guide. Even Tuff Stuff and Beckett magazines and books are also good options.
A 1990 Donruss Mark McGwire AS card number 697 has a book value of about .50 cents in near/mint -mint condition. This price is for the correct card not the error card. Professionally graded cards will sell for more. Condition is important. Common flaws with baseball cards include: rounded edges, creases, off centered, and faded color. Any or all flaws will devalue the card significantly.
Less than 50 cents.
