Bridge Blog 937-A: Exception to the rule

As a student of the spots on the cards (see Blog 902), I know well which cards are not palindromes, i.e., not the same right side up as they are upside down. Among the Diamonds, only the 7 is not palindromic, while in all the other suits the 3, 5, 6, 7, 8 and 9 have spots that can be inverted.
But at the Bridge Centre of Niagara in St. Catharines, Ont., on Friday, we ran into a vintage deck of cards that broke the rule. These were cards with bar code marks on them for automatic dealing machines – a feature that newer machines no longer require. And whoever designed them made sure that the 6s looked the same whichever way they were turned.

Afterthought: If they could put one of the middle spots facing up and the other one facing down on the 6, they could easily do that on the 8 and the 9, as well. I should have looked for it.
