To me, whether to sell or not would depend on what I needed the funds for. If it's to feed your family, keep clothes on your back and a roof over your head, by all means, sell it. If you can "get by" by other means, keep it as a sort of insurance policy in case things take a turn for the worse. I wish you the best from here on out.
I collect 1969 Mets memorabilia and 1960 Topps baseball, nothing else.
