I don't have but a fraction of what I have put into machines since 1973. But I only put in weekends back in the days. I had a ton of fun found IHs wheaties, rosies , mercs, barbers, walking libs , standing , V nickels Washingtons and Franklins Peace Dollars and other dollar coins and a lot of clad . Rings and relics old toy cars , trucks , things I have no idea what they are but I am sure they are very old. Like the cool tool or part of a buckle I use to take tires off bike rims. I got back in shape getting back in to detecting in 2010 and notice if I take time off I start to slide back out of shape a bit . All that bending down and getting up is good for you. What that is worth is way more than you can put a price on . Helps keep you alive and able to do things you wouldn't be able to do so well if you didn't go detecting eventually you could end up in a wheelchair if you didn't go detecting. I am 63 and in pretty good shape. If I wanted to I could run but chose not to anymore. Now and then I do just to see if I still can. LOL Thinking back on it all I should have been saving the copper pennies from 1959 on up to 1982 in jars one day they will be worth a lot to someone and they don't amount to that much in cash today that I can't afford to not save them but I figure I might as well use them to pay for batteries and whatever else I want . I am sure someone saves all the coins other than the zincs and who knows maybe someone is saving those.
