Dana, not a problem. The chipguide is also a great resource to see what chips are out there. See link below:

I handle the updates for PA and all of the lower denominations that are available are there. One will not appear until tomorrow because I just added it today, that is the Mohegan Sun Fifth Year Anniversary chip which comes in $5, $25, & $100.
