How to Price a Fossil

Learn How to Price A Fossil

• 1

  Accept the fact that very common fossils will not fetch much of a price at all. Some examples of common fossils include mollusks, flints, ammonites and shark teeth. Every novice collector is bound to have a box full of these already.

• 2

  Know that the exception to the above is a specimen that exhibits a characteristic not usually seen in other examples of the same kind of fossil. This small difference can add up to a significant increase in the price of the fossil.

• 3

  Understand that most fossils, particularly larger specimens, require some amount of restoration. However, this can detract from the price value of the fossil if most of its composition is artificial.

• 4

  Figure on an exception to the above, as well. If the fossil specimen is extremely rare, then restoration can actually improve its value.

• 5

  Determine how much restoration if any has been made to a fossil by examining it under a black light. Natural bone or enamel will emit a fair amount of fluorescence.

• 6

  Use a loupe which enlarges four times or more to inspect certain fossils, such as bone and teeth. Well preserved bone fossils should reveal a system of tiny cracks, while enamel from bone should look slightly glossy. Restored pieces of bone and teeth will look more grooved and dull, respectively.

  Compare your fossil or one you're considering purchasing to museum casts to help determine identity and market value. The American Museum of Natural History maintains an online reference library where you can conduct your own research (see Resources below).
