Hi Archie,

If the amount available told to me was correct, I'd "value" the chip at 1000 - 1500. That seems to be about right for 15 or so KNOWN chips which is where I estimate the amount to be. Am I off on this amount??
As for the "errors", they're hard to 'value' as most collectors I know do not actively go out of their way to collect these type of chips. To an "error collector" they're probably 'priceless' as in most cases they are one-of-a-kind examples. If I HAD to put a price on them, I'd add maybe 200-400 over the regular chips value, no more.
Since we're on the subject of BOA's, what about the 20a??? Unless I've been a mushroom these are NEVER offered......at least not as much as the 1st issue so isn't the "book" of 600-750 low???
