I am not sure on the total number jack, although there were over 100 varieties. When trick or treating, one trick was to turn what you were wearing into odd hues. If you were wearing all cloth items...you could cut them up when you changed color giving you hued halloween cloth. A quick person could attain over 30 cloth per trick, but the color itself was seemingly random. These hues are the same (as far as I know) as those attainable from the metal dye tub.
Hope that helps with the explanation. I believe this cloth can go for upwards of 500K per piece depending on the color. (of course some are more desirable than others)
