How much are a Sterlingworth 12 gauge and a 20 gauge double barrel shotgun worth from around 1900?

Answer 1

The value varies widely with condition and gauge. I think that prior to 1912 only 12 gauge sterlingworths were made. The 20s (and 16s)began production in 1912 or 1913. Usually the earlier ones are worth a little more than later (after about 1930) ones. A 12 gauge from the early years in near-mint condition would be worth around $2000, an average 12 would be in the $1000 range and one in poor shape (broken stock, pitted barrels, dents in barrels, etc) ordinarily would be worth more like $400 to $500. Twenty gauge prices corresponding to these would be about $3000, $2000 and $1000.
