Quick answer: Uncapped Poetics tomestones, which most veterans have thousands of, buy items you can resell on the market board. The current uncapped tome (Mathematics in our data) buys this tier's crafting materials, which sell fast while the tier is live. Your weekly-capped tome mostly buys gear, so spend it on gear. Check current exchange rates against live prices to find the best conversion.
Tomestones are the currency you earn whether you want them or not. Roulettes pay them, and so does every dungeon and raid you run for other reasons.
For most players they pile up with nothing left to buy. A good chunk of what they purchase is tradeable, which makes tomestones a gil faucet that costs you nothing extra to run.

Convert while the tier is live
The current-tier crafting materials sell for this tome. There's no weekly limit on earning it, but the materials lose value once the next patch lands, so convert while they still sell. Your weekly-capped tome mostly buys gear; spend that on gear.
Item counts are from our exchange data.
The tradeable Poetics stock falls into four rough groups:
Crafting materialsThe bulk of it, and the reliable earner. Old-expansion materials that current crafters and housing projects still use.
Demimateria and refined componentsSteady, unglamorous demand from crafters.
Orchestrion rollsCollectors pay well and supply is thin, because most people with Poetics never think to buy them.
Minions and faded music sheetsSlower movers, occasionally very good ones.
Current-tier tomestones are simpler. They buy the crafting materials of the moment, which sell quickly while the tier is live and lose value once the next patch lands.
That's the whole ranking. The 0.95 is the 5% market tax. The same item is sometimes offered at different rates by different vendors, so always take the cheaper exchange.
Our data has several items listed at two costs, and the difference is free money.
The Tomestone Exchange tool runs that math across every tradeable exchange (117 in total: 87 for Poetics and 30 for Mathematics), prices them live against your world, and sorts by gil per tomestone.
This tool has no filter box, so the units/day floor is one you apply by eye. A row marked also needs … costs something extra on top of the tomestones.
Prefer to tune it? The filter presets in the main gil guide explain why a sales floor matters.
Same warning as every other conversion on this site: the best gil-per-tomestone result is often an item with one optimistic listing and no buyers.
A slightly worse rate on something that sells daily beats a spectacular rate on something that sits in your retainer until the next expansion. Check sales velocity, not just price.
Materials for the current crafting tier are worth the most early in a patch cycle, when everyone is levelling crafters and building gear. Old-expansion materials are steadier but flatter.
