This is your periodic reminder:
Do you have family history items where your copy is the only copy? Make digital images of the item. Write up the history of the item. Share those with people who are interested–or may be interested. Try and find a way to preserve the item long term, including who will have possession of it after you have left this existence.
If you can’t think of someone who would be interested, it is all the more important that those digital images and written up history of the item be shared with those who have an interest in family history but may not be able to keep the physical item.
