Good story & interesting to know.
I have one (I'm sure I got it from you new, back when it was issued.)

Just being a troublemaker here but ... since postage is $2 for 1-4 chips and $6 for 5 or more chips, wouldn't it be better (for the buyer) to split 5-8 chips won into 2 packages (total of $2 + $2 shipping), rather than a single package of $6 shipping?

I'm sure the jump in shipping is due to priority mail being used, but just nitpicking ...
