Where can I find the value of a misprinted baseball card online?

It's a mistake, but it's not an error card. Cards with glaring mistakes (ex. picture of wrong player) that are not corrected are known as uncorrected errors (UER), but, that being the only card there is, there's no extra value. Cards with very minor errors, like a lack of proofreading (Jon/John), aren't worth even mentioning in a price guide.

The only time a card with a mistake becomes an error card is if a corrected card is also issued. When the mistake is caught early and very few get out, compared to many of the correct version, that is when they can become valuable.

Yours ins't worth more than any other common in the 1995 Topps set.
