I own thirty-seven things I'd have trouble explaining.
Not because they're strange, but because the explanation lives in my head. Why I paid what I paid for a particular book. Which of two nearly identical watches is the one that matters. What the receipt in the drawer belongs to. Where the fair price came from, and how old that number is now.
Every collector I've met has this problem and almost none of them describe it as a problem. It only becomes one at the exact moment you're not there to answer questions.
The three numbers people collapse into one
When someone asks what a collection is "worth", they usually get one number back. There are at least three, and they're rarely close together:
What you paid. The only figure that's a fact. It's also the one that quietly disappears first — the receipt goes, the email gets archived, and four years later you're guessing at your own history.
What it would cost to replace. What an insurer cares about. Usually the highest of the three, because it assumes buying at retail, today, in a hurry.
What you'd actually receive. What a sale really produces after fees, shipping, insurance, photography, and a buyer's premium. Reliably the lowest, and reliably the one nobody writes down.
None of these is the true number. They answer different questions. The mistake isn't picking the wrong one — it's keeping only one and forgetting which question it answered.
What I actually do
I record what I paid, with fees included, because fees were real money.
For anything without a live price, I keep a comparable: something similar that actually sold, with the date attached. Not an asking price, not a listing, not a price guide — a sale that happened. Asking prices are opinions with a number on them.
If I can't find a comparable I'm willing to defend, the item stays at what I paid. It does not drift upward on optimism. An honest cost basis beats a flattering estimate, because I know exactly how much I don't know.
I date everything. A valuation without a date isn't a valuation, it's a memory.
And I write down why. One or two lines: where it came from, what the condition really is, what I compared it against. This is the part that takes ten seconds and is worth more than the number.
The reason to bother
For a while I told myself this was about knowing my net worth, and partly it is — a collection you can't value is a hole in the middle of your own finances.
But the honest reason is smaller. If someone else ever has to deal with these thirty-seven things, I'd like them to inherit the reasoning, not a shelf and a shrug. What each thing is. What it cost. What it's roughly worth and how confident that figure is. Why it was worth having.
That's not an investment record. It's closer to a letter.
Where Khalt comes in
I built Khalt (khalt.app) because I was doing all of this in a spreadsheet that was always six months stale, and because the stocks side and the shelf side never rolled up into one number.
It holds both. Live-priced holdings sit next to things that will never have a ticker, and the things without a ticker carry what you paid, a dated comparable if you have one, photos, provenance notes, and where the item physically is. Estimated stays labeled estimated.
Nothing in it is public. There's no feed, nothing to share, no trackers, and you're never asked for a serial number or an address. There's a one-click export and a delete that actually deletes: khalt.app/help
It's free and early, and I'm looking for a handful of collectors who'll tell me where it's wrong.
