i've tracked the prices of crystal parks for almost 2 years, so i can give you my general opinions. though the demand for this particular set seems to have gone down significantly in the last year.
$0.50 - these are pretty hard to come by. when they show up on eBay, they typically fetch $3+ each
$2 - there are at least 2 versions of this chip. the more common version typically sells for between $2.50 and $3.50. the more rare version is more like $5-6. i think i have pics of them all, but you could surely look them up.
$3 - these very rarely (if ever) sell for less than $3.00
$10 - these almost never show up. when listed as a single chip, i've seen them go as high as $12, more typically around $8.50.
$25 - there are 2 versions of this chip as well (not including the "Year Of" series, and the "Opening Night" versions - both with grand inlays). the more common version has 8 split red edgespots and typically goes for $6-8 depending largely on the condition. the less common version has 4 split olive colored 1/8" spots with a red spot between. these are worth slightly more (maybe $1 difference)
$100 - drilled? don't have a lot of data on these, but i want to say $6-8 each. if you somehow have one that's not drilled, you're talking a lot more
$1,000 - i've NEVER seen one of these that wasn't drilled. again, i don't have a lot of data, but the sales that i do have recorded were in the $10-12 range. all of these have a serial number on them. for some silly reason, if the serial number is like 1000 or some other round number, people will pay more.
by the way - i might be willing to take that $10 chip off your hands
hope that helps a little,
