TCR#10 lists the following 2 chips from the Riviera: 
 
- E2371  B  ltblue  house  3burnt orange  OOR-Multi-FG   yellow    "Cow Chip"               2002 
- V9635  B  ltblue  house  3burnt orange  R-white        whi,pink  "Rodeo Days 2001"  1200  2001 
Aside from the Inlay description ("Cow Chip" vs "Rodeo Days 2001"), the main differences between the chip listings are as follows: 
 
- E2371 has OOR-Multi-FG inlay, V9635 has R-White 
 
- E2371 has yellow denomination, V9635 has white,pink 
 
- V9635 is listed as LTD 1200, E2371 is not 
 
- E2371 has a date of 2002, V9635 has 2001
I have attached a scan (both sides) of what I think is V9635.  I am basing this on the LTD 1200 and the color of the denomination. 
 
I have looked around and have asked around and cannot find an example of E2371.  Anyone out there have one?  If so, I would be interested in a trade. 
 
Thanks for looking...Jim
