The blue book shows the #22 having the slots going all the way accross and the #23 having a center divider separating the slots, ie. the 23 has twice as many slots. As with almost all cases supply and demand determines the price. The more rare the more expensive. Jon Haussler's pan book list the #22 as having 12 variations all with a rareity of 1, and the #23 with no variations and a rareity of 4. So, the #23 is worth more but, still not being really rare. His rareity scale is 1 thru 10, with 10 being the rarest. C B
