Puzzle card symbols

Please see Brian Enigma's impressive Card Catalog for a sorted, comprehensive listing of cards.

General

Some of the cards have faint playing card symbols on. It has been speculated on Unfiction that these may be a deck order for a solitaire cipher appearing on Card 243. So far, all symbols appear on cards with prime numbers, so this list will reflect that, until proven otherwise.

A chart showing cards in order:

Note the groupings of playing card symbols goes Club-Diamond-Heart-Spade, from Ace to 2 (ace high), forming 13 sets of 3 letters.

Other notes:

• Don't trust the black colouring 100% in the card catalogue - there may be a couple of cards that don't match by that alone - the original card should be re-checked to ensure accuracy of the black colourings.
• Cards aren't necessarily evenly cut down or across the middle of each letter, making calculating possibilities difficult.
• The font used is a simple thick seriffed font.
