I and most of us have made either minor or major mistakes in collecting. I must say I recovered nicely from mine over the years. These Rebel swords as UVCRelics stated are the "most faked CS items". I watched an auction recently waiting for the item I wanted to come up to bid. There was a Nashville Plow Sword estimated to go at $3000-5000. I watched it skyrocket to $10,000. That did not include the house premium of 20-25% and possible taxes. I collect the Union side and if by mistake or someone's error I end up with something CSA (as in my Enfield) then so be it. Simple put I can't afford CSA item prices. BUT if I was a collector buying CSA items I would want someone like Mr. UVCRelics standing besides me giving me a tap on my right rear should saying it's good to go or a tap on my left rear should saying it's fake and don't touch it with a 10 foot pole!
P.S. I did something similar to that over 40-45 years ago as a young collector at shows. When there was no Internet. Saved me from getting ripped off.
