What about with a drill press?

You could bundle the card on top of a stack of cardboard cards (or
plastic, or whatever you are reproducing onto). Clamp them all together,
and then use a drill press to line up exactly on top of the original card
hole, and drill down thru the stack of reproduction cards.

Just an idea.
