There was a Net54 thread on this not so long ago, but search is not my friend tonight. The gist of it, IIRC, was that there are a number of cards in the AB realm that have relatively normal borders. I have no clue whether this was a general statement or if it only applied to certain instances of those cards.
My exposure was only to Pirates - the Leifield (350NF) and Miller (350F) seem about normal - the others were all much narrower.
