A few days ago Robert Eisenstadt offered a photocopy of his Kernen Mfg. Co. Pocket Catalog of Poker Chips. I purchased a copy which Robert was kind enough to send before he received my $5. (BTW Robert, I mailed the $5 yesterday.)

Printed under several of the poker chip descriptions is, "Coppers, Markers and Splits free with each rack of Checks." I know what coppers and markers are, but what is a split?
