The case of the missing coins (continued)

I've been re-reading some of the Father Brown mysteries (in Thpanish, of course), which has prompted me to do a little detective work of my own. Specifically concerning the puzzling shortage of coins here in Buenos Aires. I am beginning to form a little theory of my own.

My initial reasoning was as follows. Any shortage must have a beginning (and - one hopes - an end). So I began to examine the dates on all coins that did come into my hands. The results so far can be summarized in the following two-by-two table:

************* Before 2000 ********** After 2000

Small coins .....................0.................................14

Large coins ....................12.................................0

Here, "small" refers to both the size and denomination (5- and 10-centavo pieces), as does "large" (25- and 50-centavo and 1-peso coins). Numbers in the table represent frequencies (the asterisks and dots mean nothing, they are just to trick Blogger into making a halfway readable format).

Me parece interesante. Voy a continuar mis investigaciones.

I know y'all are on edge to get to the bottom of this. You can rely on me. I'm all over it.

The plain people of Ireland: Could you describe your sampling procedures in a little more detail, to allow the reader to get a sense of the generalisability of your results?
The management: I could, but I don't feel like it. Please go back to your caves.

Oh, it pains me to see you resorting to ASCII graphics. That's so 1987! Didn't you get a copy of MatLab to take with you on your retirement?

But I'm here in the internet cafe. Where this particular computer insists on speaking to me in Chinese (not kidding).
