My Dad had an Antiques Road Show moment at a garage sale a few weeks ago. Picked up an 1864 Fayetteville rifle for $200.00. We've been searching the web and have found the same rifles with the exact markings sold for $7000.00 to $30,000.00 depending on condition. This gun is rough, so I know it will go on the lower end. Can anyone recommend a reputable Auction site that they have actual experience with? Dad wants to sell!
