Hi FFG!
Looking at your shop pages for the new tokens, your dimensions state they measure 1.4mm by 0.4 mm. This would make them less than 1/16th of an inch in diameter, and about as thin as one of your standard cards. Looking at my Citadels counters, I think you mean 14mm (1.4 centimetres) by 4mm (0.4 centimetres).
