Every tin has a price.
Every price has a story.
The Tin Finder is a collector's archive of pipe tobacco — what it was, what it cost, and what time has done to it. Browse the cabinet, follow the price notes, and read the story of a shop that never threw a ledger away.

On the shelf
A few tins worth knowing.
The collector's cabinet
Real tins, with their order slips.
Six tins from the curator's own cabinet, with the names, years and prices recorded on the October 2026 order slips. Addresses and order numbers stay private.
From the ledger
The price goes up.
The notes stay.
Every entry in the ledger carries a date, a tin and a number. Some of those numbers went up; a few went sideways; and a handful of blends disappeared altogether. These are a few of the movements the archive still argues about.
Reference values are archival notes, not offers.

Write it down, kid. A price is a promise to the future.
The story
One shop. Forty-one years of notebooks.
Walt Callahan opened a pipe shop on Clement Street in 1976 and began writing down what every tin cost two years later. What started as bookkeeping became a habit, then an archive, then — after the shop closed — a small group's stubborn project to keep the notes readable.
The Tin Finder is not a shop. Nothing here is for sale. It is a reading room for people who care what a tin cost, how a blend changed, and what a sealed tin might be worth.

The ledger lives in the Richmond District.
The cabinet is open to visitors by appointment — pipes, tins, and the original notebooks. No tobacco is sold on site.
