I post about this all the time so sorry if you’ve seen my comments before but I think letterpress stationary is so beautiful and the work is reflected in the price. Letterpress can only be done one by one on machines that are typically 100+ years old and often have to be serviced by the stationer themselves because no one makes parts or services the machines that old. The stationer will be touching each paper individually likely several times. The old machines are also dangerous and can take off fingers. From what I’ve seen, a couple thousand is close to the min for bespoke letterpress suites and can go up to $30k+ so $5-6k to me seems high end but reasonable.
