Koenig is a well known supplier of good hardtops, and if yours is complete and undamaged, you may find a buyer in your northern area. Hardtops don't sell in Texas too well, but in Colorado and Oregon and other northern states they are practical. If you do decide to remove it make certain you keep ALL the hardtop related parts together. Many times the pieces that the doors attach to are lost, as well as any joining pieces between panels. Even save the hardware, no matter the condition.
Pricing, depends on the season and demand. Minimum $50 for a hardtop with missing doors, max $750 for a fully restored top ready to bolt on. Damaged, severely modified or homebuilt ones are usually scrapped. They do work well for keeping the rain out of your parts jeeps .......
