I recently hit the Blue Lake Casino in Northern california and picked up a few chips. you can see the 50 cent through $25 chips on the chipguide at:

I took some pictures but they did not turn out well, the $100 is sort of in focus and I will try and post it later. If anybody wants chips I have
Chipcos
50 cent X4
$1 x7
$5 x1
They are a bit faded but were the best that could be found in the racks at the tables

$1 Slot token x3 (sory no uncirculated available) I did not get a $5 slot token and they were realy beat up
I did not keep any $25 or $100s but could possibly get some before going home next week.

On the Hupa Indian reservation at the Lucky bear casion

(the $25 are actually Green and they have a $50 that is BLUE)
They have new slot tokens and I got 3 each of the new and old styles(once again no uncirculated available)
I have available chipcos:
$1 x5
$5 x3
$25 x1
$50 x1
All are very new and clean

I will try and get some better pics of the chips not on the chipgiude so they can be added. neither casino wil sell any chips from the cage. The $50 was noton the tables and the dealer had one delivered for me. It was interesting to have a single chip delivered by security in a full size chip carier made to hold 8 or 10 full racks and the supervisor come and sign it in

I am not sure if I will be able to hit blu lake again or not but will be able to get to Lucky Bear again. If anybody wants $5, $25, or $50 let me know ASAP as $25 and $50 will require paypal before I buy them. 450 was the largest chip at Lucky bear, and Blue Lake had Black $100 and Purple $500.
