How this is worked out
Collection Inventory
A worksheet for the family: what it is, where it sits, what was paid, the papers, who it matters to.
Or paste a list, one item per line. Fields in this order, separated by a vertical bar: what it is, where it sits, what you paid, year paid, latest appraisal, year appraised, papers, who it matters to. Nothing you type leaves this page.
Your answer in words. Add what you own: one card for each piece. Nothing you type leaves this page, and the page keeps nothing.
Some choices came from your profile.
