To take this in a philosophical direction, what is a cookie? I think we can all agree Miguel Dilone is a cookie, but (looking at the snapshot usage table boogerlips so kindly liked above) what about some of the other frequently used players? 1986 Raines ($6.1 mil), 1923 Williams ($6.2 mil), and 1985 McGee ($7.1 mil) are all high up on the list, but given their prices for a relatively inexpensive position, are they really cookies? Or are they just good performers? I'm sure somebody more mathematically inclined than I has done a value analysis; at their prices, I would be surprised to see that they provide values significantly over their costs. Also, are scrub players considered cookies? Of the top twenty most frequently used batters, 12 are under $250K.
So, how do you define cookie? Or, to paraphrase Supreme Court Justice Potter Stewart in Jacobellis v. Ohio (1964), we can't define a cookie, but we know one when we see it.
