I've got 4 matching stainless 5.5" .45 Colt of these.
They are collectable and can get a $100.00 plus premium over the normal Vaquero selling price.
You just might need to be patient until the right buyer comes along.
In 1997 Ruger began marketing the first models of their engraved Vaquero series. Offered initially only in .45 Long Colt Caliber, engraved Vaqueros were eventually produced in 12 different models, blue/case color or high polish stainless, 4-5/8" or 5-1/2" barrel lengths and in additional calibers of .357 Magnum and .44 Magnum. The guns featured a gold filled triangle of machine cut scroll engraving between each of the cylinder flutes as well as simulated ivory grips. The models did not prove to be successful as the consumer market decided that the engraving that was there was not representative of the significant additional cost to the buyer. The known serial number ranges and estimated quantities produced of each of the 12 models are as follows:
BNV-44IE (.45 L.C., 4-5/8" barrel), 56-44251 to 57-20325 - less than 1,500
BNV-455IE (.45 L.C., 5-1/2" barrel), 56-23192 to 57-15224 - less than 1,750
