I don’t know. I guess it really depends on the condition of them. But even if you had them in brand new condition, your buyer is gonna be someone that is wanting to mount bassani tips either because they messed up their own, or just like the look of the bassani tip. Try searching the marketplace and gauging what others have gone for.
I bought a set of those tips with baffles years back direct from Bassani for $80 ea. if memory serves. I actually liked the baffles, but the packing lasted like 1,000 miles lol. Need to get on to summit and buy some better stuff to re pack them.
