Context & meta
Coinage is a Castle Age economy technology researched at the Market. The upgrades record gives a cost of 200 food and 100 gold with a 70-second research time. Its official help states that Tributes to other players cost only 20%. Coinage therefore improves the efficiency of sending resources to an ally, while leaving Market buy and sell fees unchanged. It is not a combat upgrade and it does not create resources on its own. Its SEO value is in the clear team-game question: when the next transfer is large enough, paying only one fifth of the tribute is better than keeping the resources locked on the wrong side of the alliance.
History & balance
Coinage is the first dedicated tribute reduction in the Market path and sits in the Castle Age, before the complete removal supplied by Banking in Imperial Age. Its 200-food/100-gold price makes it accessible while an alliance is still building its first coordinated army, but the 70-second research time asks for intent. The official effect is narrow by design: tribute costs 20%, while Guilds belongs to commodity trading and Caravan belongs to Trade Unit movement. Coinage has always been a coordination technology in practice because its value depends on another player being able to turn the transfer into Villagers, units, or upgrades at the right moment.
In pro play
Research Coinage when the next resource transfer is already visible. A Castle Age player who sends one small emergency payment may not recover 200 food, 100 gold, and 70 seconds; a player funding an ally's second Town Center, Castle, or army can recover the investment quickly. Queue it at the Market while the economy still supports production, then send resources in deliberate packets instead of many tiny losses. Coinage is most useful when one civilization has surplus food and another needs gold or stone for a timing. Keep your own unit production safe, because a tribute technology that delays your only defense is not an economic win.
How to counter it
Coinage has no combat counter. The classic mistake is researching it without an imminent team transfer, or delaying it until the Castle Age window that needed cheaper tribute has passed. The official help gives one verified effect: Tributes to other players cost only 20%. Use that number to decide: compare the saved tribute on the next planned packet with the 200 food, 100 gold, and 70 seconds, then research before the transfer rather than after it. If you keep missing team-game timings without knowing which economy technology to research or when, AoE Coach reads your match-up and gives you the resource plan and timing.
