Some years ago I purchased a HP 19Bii while I was attending an MBA program. I had to move out of the place I was living at the time, so it got misplaced during the move, and placed in a box that went overlooked for years. I recently came across it and realized I had not sold it.
I don't need this calculator anymore, and I friend of mine told me it could be of value to collectors considering it is still in the original packaging.
I took a look on eBay, but I can't really figure out how much it would be worth.
Would anybody have an idea of the market value of this calculator?
