Your trays appear to be plastic with flock coating. Perhaps another possibility is to consider upgrading to the Abafil system, with
wood and leather
style trays with velvet cloth? Since you are thinking of spending
money on
red trays anyway, this may be an upgrade opportunity.
Abafil deluxe trays have multiple advantages over other systems, with recesses that are generally deeper and thus better accommodate thick tetradrachms and bronzes, and with padded undersides preventing damage to the coins below. They also come double-depth for extremely thick coins as an option. And they look stunning.
