What is the value of a Yogi Berra signed baseball card only one of five made?

A Yogi Berra signed baseball card is worth between $30.-$60. Value is based on average prices of recently closed auctions. Prices may vary based on condition, and the type of authenticity that accompanies the signature. Signatures that have not been properly authenticated could sell at half the market value or less. Add for inscriptions. Because there are far more than 5 signed Yogi Berra baseball cards in the world, the one in five limited edition means nothing. The card is limited to five made, not the signature. In general, collectors of baseball cards would rather have a baseball card without the signature. The signature would be considered as a flaw in the condition of the card and will lower the value. An inexpensive card will benefit, but if the value grows in the future it will be held back by the growth of the value of the signature.
