Quick answer: Grand Company seals convert to gil through Expert Delivery: turn in cheap dungeon or vendor gear for seals, then spend seals on items you can sell. The seal reward scales with item level, so the cheapest high-ilvl gear per seal is what you want. It's a steady, low-effort loop once you know which turn-ins pay best.
Grand Company seals are a currency almost every player has and almost nobody spends deliberately. They're also one of the few currencies with a clean, repeatable conversion into gil.
Seals are capped, so the gil you don't convert is gil you throw away.
Hand market-board gear to your Grand Company's Personnel Officer under Expert Delivery and you receive seals based on the gear's item level. Spend those at the quartermaster on something tradeable, then sell it on the board.
It's a currency exchange. It pays as long as you buy the right gear going in and the right goods coming out.
Expert Delivery pays purely on item level. Nothing else about the piece matters: not its slot, not its job, not what you paid. The payout follows two rules:
The two halves meet exactly at item level 200, worth 1,150 seals. Below that line each point of item level is worth 5.75 seals. Above it, only 2.
High-end gear is far worse per item level than mid-range gear. An ilvl 600 piece pays 1,950 seals, barely more than something a third of its level.
Sort any list of gear by "cheapest gil per seal" and the top results will be garbage: low-level pieces with a single 1-gil listing and no sales at all.
The ratio is spectacular and the item is unbuyable in any quantity. You can buy one. You can't build a routine on it.
Only consider gear that's actually being traded. Our GC Seal Deliveries tool has that filter on by default. It cuts the candidate list by roughly two thirds. The tool scores 7,262 eligible items (everything equippable, marketable and with an item level) by gil per seal on your world.
Looking for a specific slot or set? Use Search gear…. Sort by Most seals to see which pieces fill your balance fastest per turn-in.
Expert Delivery is the source that scales, but seals pile up on their own from:
Supply and provisioning missionsThe daily crafter and gatherer hand-ins.
Hunt billsThe daily and weekly mark bills from your Grand Company board.
FATEsIn any zone, while you're doing something else anyway.
FrontlinePays seals generously for a single match.
The quartermaster sells a mix of untradeable convenience items and genuinely marketable goods. The marketable ones close the loop.
Ventures are tradeable, for instance, and anyone running retainers buys them constantly. That makes them a reliable seal sink with a real buyer base.
The rule is the same as for any currency conversion: rank the tradeable stock by gil per seal on your world, then check that it actually sells. A high price on something nobody buys isn't a conversion. It's a retainer slot with a story.
Rows tagged with a company name and only (banners, furniture, portraits, orchestrion rolls) are sold by that Grand Company alone. Gil per seal already takes off the 5% market tax.
Spending a big balance? Sort by Units/day to find what the board can absorb, and don't list more than about a day's worth of anything. Same logic as the filter presets in the main gil guide.
Every dungeon run hands you gear you'll never wear. Here's where it can go:
NPC vendorThe default instinct. A few hundred gil and done. Usually the worst option.
Expert DeliveryUsually worth considerably more in seals. No listing, no tax, no waiting.
DesynthesisMid-level gear whose materials are in demand is often worth more broken down.
One honest caveat: a piece can go to seals or to materials, not both. Genuinely worthless gear should always become seals.
