Ruger Collectors Association

Two Ruger New Vaqueros 45cal revolver, single shot. Intricate engraving on the barrels done by the manufacture. Consecutive in serial number and engraved with 1/1000. Kept in a case and never fired. Any idea what the value is?

Really need detailed photos to try to determine anything. You should also get a letter of authenication (LOA) from Ruger, they're only $10 each and they will give info to help determine the value.
