I have a CASIO MQ-12 calculator that I would like to sell. It is in beautiful condition (all functions work/no scratches). It comes with a leather case. New batteries. What is the value of this unit?
I would guess around $50. One just sold on eBay for $32 but the owner couldn’t power it up and assumed the battery was dead.
