It’s not the most expensive. You can see a few entries above yours that a B30 in box leather was slightly more expensive and there are no other comparable entires (same bag size, same currency, chevre) to draw a conclusion from. My understanding of the Chevre leathers from SLGs is that Chamkila is more expensive than Mysore, but I’m not sure where coromandel fits in as it was just recently re-release, I believe. Anyway, H has its own secrets for pricing differences for leathers based on the supply costs to obtain the skins and then whatever processing is necessary to perfect the skin, and the price difference is usually “in the noise” compared to the basic expense (ie +/- a couple hundred dollars out of 10,000).
