JarSort

The fine print, in plain language

About JarSort — and the rules it runs on.

About

JarSort is an independent, one-person project built for a specific moment: someone inherits a jar, a coffee can, or a cigar box of US coins and has to decide — before a dealer does it for them — what is spendable, what is metal, and what deserves a second opinion. It covers US and Canadian coins, plus the handful of world-bullion coins that turn up in the same jars — Krugerrand and Britannia — on purpose: a narrow catalogue, checked deeply, beats a shallow one of the whole world. Canadian jars — and plenty of American ones near the border — are full of pre-1967 Canadian silver, so the Canadian series are documented to the same depth, with the silver changeover years (1967–68) handled explicitly.

JarSort is live, and paid plans are available through Stripe checkout. Prices on this page are a dated market snapshot — researched on Oct 24, 2026 from dealer asking prices, published buy sheets and price guides, with silver at $53.80/ozt (Kitco); the few series without verified data keep seeded ranges, labelled as estimates in place. The sorting flow, the deterministic pricing, the checklists and the exports you see here are the real product logic.

One coin, three chapters

Every coin in the jar has already lived a life.

The route a typical Morgan dollar took to reach your kitchen table — and the ninety seconds that finish the story.

1883 · NEW ORLEANS

Struck

Pressed at the New Orleans mint — the small O under the wreath on its reverse is that mint’s mark — in the years when Morgan dollars were coined by the tens of millions and spent like ordinary money.

1883–2026 · DRAWERS, CANS, ONE JAR

Held

It outlived a century of house moves and clear-outs because every owner, in turn, looked at it and decided it seemed too old to spend. That instinct is usually right — and it is never priced.

2026 · YOUR KITCHEN TABLE

Verified

Ninety seconds with JarSort: year and mint mark confirmed, three sourced prices, one of three piles — sorted and written down before any dealer ever sees it.

Both faces of an 1883 Morgan dollar — drag the slider to compare the obverse and the reverse
Obverse Reverse
← ObverseReverse →

Two photographs, two different 1883-O specimens of the same design. The reverse is where the mint mark hides — above the DO in DOLLAR — and it is the side most people never think to check.

Why now

The demand is measured, not guessed.

And it keeps being refilled by inheritance, cleanouts, and metal prices — not by collectors.

+148%

Rise in the silver price during calendar 2025, to a record — mechanically re-pricing every pre-1965 silver coin sitting in a drawer. Perth Mint, Dec 2025 market update.

Questions about a coin we sorted wrong, a catalogue gap, or a plan: email hello@jarsort.com. Every message is read; replies usually land within two business days.

Please don’t mail coins — we can’t accept, store, or return them, and no valuation can be given for a specific coin by email. For anything in your “worth a closer look” pile, a local dealer or coin club, dealer sheet in hand, will serve you better.
