My dad passed away 3 years ago and was an avid metal detector. My mom is now ready to let some of his things go, but I have no idea what they are worth. He has 2 Tigershark Tesaro and a Minelab Explorer SE Pro. He still has the boxes, paperwork and all the stuff that came with them. Can anyone advise me on what to ask for them and where do you think I should try to sell them? Has anyone had pretty good success with the classifieds on this website? Thanks in advance for any advice.
