Pounded and aged coin tea
Steamed leaf beaten in a mortar until it is a paste, formed into discs with a hole through the middle, dried and then held while a slow microbial change works inward. It is the only route in the catalogue whose leaf never exists as separate leaves after the second step.
What makes this route what it is
Structure is destroyed rather than shaped, and it happens at step three of six. Every other route in the catalogue preserves the leaf as a discrete object — twisting it, curling it, flattening it, compacting it — because everything downstream, from grading to brewing to breaking a cake, depends on there still being leaves. Here the leaf stops being an object early and the rest of the route acts on a body instead.
The route, in order
Each note describes what the step is doing in this route. The same operation does a different job in a different chain.
Substantial leaf rather than a bud pluck. The route asks for material that will hold together as a mass, and fine spring buds have neither the substance nor the price to justify it.
Fixation, and also the softening that makes the next step possible. The two purposes are inseparable here in a way they are not in a sencha manufacture: the leaf has to leave the steamer hot and fully wet, because it is going straight into a mortar.
Beaten until the batch stops being separate leaves and becomes one cohesive mass. This is the step the route exists for, and it is the only one that cannot be performed at any other time — the window closes as the leaf cools.
The paste is formed by hand or in a small mould into discs with a hole through the middle, so that pieces can be strung for storage and carrying. Forming rather than pressing: the mass is already cohesive and the mould is giving it a shape rather than forcing one on it.

Drying
Slow, and slower than a pressed cake needs, because a formed disc has no internal air channels for moisture to leave by. Hurried here, the outside sets before the inside is dry.
Held while a microbial change works inward from the surface. With almost no air inside the body, the outside and the inside of an old piece do not change at the same rate, and a piece broken open can be noticeably two teas.
How it differs from its neighbours
A route described on its own teaches very little. The useful fact is always which other route it is nearly identical to, and where it leaves it.
One position in the route is filled by a different named method. The shape of the route is unchanged.
One slot, and the difference decides how the finished object behaves in the hand. A sheng cake is separate leaves compacted under force and comes apart along them with a pick; a coin is a body with no leaves left in it and has to be snapped or dropped whole into water. Buyers who bring a pu-erh pick to a coin conclude the tea is badly made, when what has happened is that they brought the wrong tool.
This route leaves out an operation the other performs. Omissions are usually irreversible — the step cannot be added back later.
No sun-dried maocha stage, and it is not an economy — it is structurally impossible. The pu-erh route dries its leaf and stores it as maocha for months before anything is pressed, and this route has to reach the mortar while the leaf is still hot from the steamer. There is no point in this manufacture at which a saleable loose tea exists.
Where it goes wrong
The pounding has one window. It can only be done on hot, fully wet, never-dried leaf, and a maker who lets the batch cool has made loose tea and cannot go back — which is the opposite of compression, where a finished tea can be pressed years later. Drying is the other failure: a formed disc is dense and dries from the outside in, so a piece taken too fast case-hardens and holds moisture in a centre that then spoils inside an apparently sound object.
In full
Every other pressed tea in the catalogue is made of leaves held together. A pu-erh cake is loose leaf that was steamed to pliability and compacted in a mould, and it can be prised apart along the leaves it was made of, which is the entire basis of how it is broken and brewed. This one cannot, because there are no separate leaves in it. Steamed leaf, still hot and never dried, is pounded until the batch coheres into a single plastic mass, and only then formed — into small discs with a hole through the centre, which is a carrying feature rather than an ornament, since the pieces were strung. The discs are dried slowly and then held, during which a microbial change works in from the surface of a body with almost no internal air. The result is boiled rather than steeped, often with ginger. It has no counterpart anywhere else in Korean tea, where everything else is a pan-fired green or a variably oxidised balhyocha, and its survival is not continuous: production nearly stopped, and what is made now follows a deliberate local effort to bring it back rather than an unbroken line. That is worth stating plainly rather than smoothing over, because a revived practice and a surviving one are different kinds of evidence about how a tea was made.
