If you're talking about the Sharps Borchardt Model 1878 Military 45-70 Rifle with Scarce J.P. Lower, Denver Col. Retailer Markin, then it only went for $1,100. A bit of a disappointment
HOWEVER, if you're talking about Cased Model 1902 Georg Luger DWM Semi-Automatic Carbine with Gold Inlay. Well that went for $100,000.
