What is the value of an autographed Wheaties cereal box with Cal Ripken's picture?

The Wheaties, Cal Ripken Jr. 2131 consecutive games and counting cereal box with his facsimile signature is worth about $5.00 - $10.00 in mint condition unopened still filled with cereal. When they first came out in 1996 they sold for about $10. - $20. there were plenty available, and everyone that wanted one got one. Now with low demand, they sell for half that price. If you had the box hand signed by Cal Ripken Jr. the cereal box becomes an item to display the signature, and looses value as a collectible cereal box. The price of the signed cereal box now relies on the value of the signature and how well it displays. A Cal Ripken Jr. signed cereal box could sell between $150. - $200. Price may vary based on condition of the box, signature, and the type of authenticity that accompanies the signature. If the signature is not authenticated it could sell at half the market value or less. I will leave a link to a price guide for Cal Ripken Jr. signatures on other items.
