How much for a used Custom 2400kt ?

I recently re-acquired a custom 2400 KT that I purchased for my father in 2017. Since I have very little interest in keeping the gun, I am considering selling it. Unfortunately, I cannot remember how much I paid for the gun nor can I find any examples for sale to get an idea of a sale price. The gun seems to shoot really well and is in very good condition other than a couple small rust spots on the barrel.

Any suggestions on a sale price would be greatly appreciated. Thanks
