He shows a:

500.00 Chipco ORG + YEL With a note....Sample? Plus the 21 on chipguide.com.

I agree, probably typo on the $25.

The two $100.s listed in his 2003, Vol 1, 2nd Edition are:

100.00 H&C BLK 3 BLU/PNK/BLU

100.00 HHR BLK 3 ORG 3 YEL

These two 100s would match the two shown in my scan and on chipguide.com. I've not seen nor heard of a 100. BLK 3 ORG 3 PURPLE.
