Help please with Large shell collection

[paul monfils]

A Conus patricius in perfect or near-perfect condition might sell for $4.00 to $10.00 depending on size and degree of perfection.  A significant chip in the lip might reduce the price by 50%, and many collectors won't buy a chipped shell of a common species at any price since perfect specimens are readily available at a low price.  As in any species, a really exceptional specimen, huge size, unusual coloration, etc. might bring a higher price.
