You don't give enough information on the teddy. Different makers, details, size, condition all effect the value. Steiff is probably the king of all bear makers and highly collectible. Most noted by the Steiff button in the bears ear. Older Steiff bears in good condition can sell for $100+ per inch. Other things to look for in highly prized bears are long snouts, jointed limbs, glass eyes, humped back with straw or excelsior stuffing. Condition is of utmost importance.
