How much of your collection have you cataloged?
Consider taking your spreadsheet a step further; add photos and provenance.
Whether your collection is small or massive; by assessing the values you can decide if you’d like to buy separate insurance or simply add a rider to your current homeowner’s policy.
It’s likely the most emotionally intense way to add a piece (especially a missing piece) to your collection but the least impact on your pocketbook or wallet… trading!
No matter the method of acquisition if you get what you love then you’ll always love what you have.
There is such a thing as the unconscious collection but once you are aware of it -well- it ceases to be unconscious, doesn’t it?
