I would have to keep it. I have been trying for over 30 years to get one of my grandfather's guns. He had three. The older I get the less I am attached to material things without sentimental meaning. With the sentimental things I keep I try and find a purpose for them. Rather it's actual use or just decoration. Tough decision for you to make,and only you can make it. If kept it could always be stashed somewhere handy--just in case!
You could find out how much it will bring and weigh that with how much overtime you would have to work to keep it and still get what you want. If kept you could look at it as an investment for the future since it will probably only increase in value. When I went through some tough times years ago I sold off most of my collection,except for the sentimental ones. Thankfully most of my sentimental ones don't have a lot of value so that made it easy.
