Jim, I believe, said the top ten can come from any source NOT just the chips you own. Next up for interpretation is what is a top ten chip. I know in baseball I wouldn't include utility players.

If you think the top ten should be a cross section of chips maybe that is what jim should do. eg: top roulette, top $5, top $1, top fractional, top $25, top chip valued in TCR under $50, top chip valued $50 to $200, top hot stamp, top inlay, etc

However, as it stands, I personally consider David's chips the top ten. (at any rate the top ten chip that I wish I found in a flea market)
