I believe the T&S molds for the CPS chips cost $10000. I don't know if that was for just one or for both molds that were made, but suspect that it's per-mold. I don't know if the T&S molds are a modular design, but I suspect so.
The mold cost quoted by the original BLGOP supplier was $4000, and it was modular in design (the quoted cost was for the outer ring portion only). The modular molds planned for use in the BLGOP run were designed so that the mold ring component with the chip face (cross-hatched T&S symbols) could be interchanged with something else. The base mold (including the spot configuration and plumbing) was a separate piece and was not quoted, since the factory already had those mold components (previously used with the PWGOP chips from mrchip.eu).
So logic would indicate that the smaller of the two mold components (ring) costs $4000 and the more-complex mold base component (containing spots) would cost more. That makes PGI's referenced $10K per mold cost look about right, since both pieces were required for the CPS chips.
PGI noted that one of the CPS molds had been broken and repaired; unsure what broke exactly or how much it cost to repair. But I do know that using old molds is one of the reasons that subsequent production runs of china clay chips start having thickness consistency issues.
A minimum run of 30,000 chips (typical requirement) would put the cost of a completely new mold at around 33c per chip, on top of a factory baseline price of 10c-15c per chip. After adding art fees and shipping, the final chip cost should be in the 50c-60c per chip range (plus whatever profit margin is required by PGI, if going that route).
