Informational rates
These figures describe written chronology work. They are not a checkout, not a subscription cart, and not a mint-store price list.
Portal Trail Base charges for time spent reconstructing mint history. Nothing on this page can be purchased through the website. If a figure fits, call or email the Bangkok desk. We confirm the series line in conversation and send a plain-text estimate. There is no payment form here.
Mint chronology brief — from 4,800 THB. One series spine, dated mint cards, and a short note on conflicting public stamps. Estimate factors include how many exclusive windows sit on the line and whether club minutes arrive in mixed languages.
Series drop timeline — from 7,200 THB. A ruler across a franchise with first-digital, exclusive, and later-mint ticks. Longer cosmic team books cost more simply because more windows exist, not because we assign investment weight.
First-print digital notes — from 3,500 THB per issue cluster. A cluster is a short run of related origin or anniversary issues, not an infinite catalog.
Collector archive walkthrough — from 2,200 THB per hour. Phone or reading-room time. You keep your files; we keep a written order of mint windows.
Edition window comparison — from 2,900 THB per pair. Two windows, facing pages, no ranking.
Travel inside Bangkok, if a club wants the desk at a meeting, is quoted separately as transport time. We still do not take card details through this site.
These rates never include marketplace fees, gas, or collectible purchases. Portal Trail Base does not hold funds. Public secondary numbers some collectors copy from Binance-compatible screens remain outside the invoice. The invoice is for writing.
