Any information on the marking a deck of cards would be appreciated.
I need to number the cards from one to fifty two.

To be seen by everyone, or just by you?

Sharpies of either contrasting or "blend in" colors respectively should do the job.

It's just like the Ted Lesley marked deck, but with numbers.
I prefer not to use the press on numbers. I'd rather used some kind of fine point marker.

I find it far better to remove some of the printed ink with an Exacto knife, leaving a white space, than to try to add any type of ink.

If you don't need the marking to be subtle, but able to get by the average spectator, there is a system I use from Hidden In Plain Sight by Kirk Charles - no, not the Wild Deck, which I think is a fine deck, but I believe it's called the Farmarx System (I may be misremembering, but it's in the book).

Hope this helps.

The old guys dangle a ballpoint pen tip in a small vial of alcohol to get a thin solution that they painted on cards like daub.you must experiment to get your proper hue.
