Wow...Ive only been detecting for 7 years or so, But I also have a huge collection of things I have found that haven't parted with yet.
My plan was to keep them to see if the kids may be interested one day, but every now and then I do purge out some things.
And to be honest, I have grown attached to alot of it, not of the Item itself, but the memory of when and how I found it.
There are so many items that I can remember vividly finding and remembering who I was with and most of that day.
Maybe its just a mental thing, but I do enjoy being able to go thru them all every once in a while. Lately I have been thinking of Selling and Giving alot of it way, There are alot of people on this site that have passion for many different types of things.
For instance, I find alot of old Shotgun shells and Axe Heads, Farm equip, etc. But being on this site, i found out there are people that collect these things.
Again, I dont nearly have the hours/years you have put in, so my feelings might change. But I would think giving it to someone that collects these things would be a great thing
BTW, I collect Silver and Gold..lol
