I have consigned 20 gauge Superposed guns with minor warts to auction houses. The minor warts, square knobs, short tangs, recoil pads, 26 1/2" barrels, short stocks, less than excellent condition, etc. Invariably, a single wart results in a net received price of less than $2000. At the same auction house, a gun with none of those warts can result in a selling price in excess of $4000. A steel trigger, solid rib, field choked gun in high condition can sell for twice that.
