They're plentiful and frequent on eBay. As with almost everything, price depends largely on completeness and condition
(and older
ASB games are often missing player disks or include many more than were originally provided),
but with games produced in multiple (annual, in the case of
ASB, APBA, Strat-O-Matic, &c') editions and variations,
price varies widely depending on which year's edition.
Dave will be looking for a pre-1956 edition (but probably not '54, although box lids often feature with the previous
or following year's edition). In addition to eBay, Dave, you might want to check out the
ASB discussion group at
https://groups.yahoo.com/neo/groups/...eballGame/info
-- longtime fans there occasionally have vintage editions for sale at very reasonable prices.
Gary, which year's edition do you have? The copyright date is not an accurate indicator, as it was retained until
the box design was again changed. If you're unsure, just list the pitcher disks from your game and we'll tell you
what year it's from.
