Need help on the following chips if anyone is familar with their difference(s):

Harrah's .25 PINK H&C 3WH/6LAV - R-WH - red "RENO" -- N5129 (Pg 106 TCR)
Harrah's .25 PINK H&C 3WH/6LAV - R-WH - pink "RENO"-- N5140 (pg 107 TCR)

I need to confirm that
(1) They are DIFFERENT chips... correct?
(2) If anyone has a scan of BOTH of them -- maybe side by side (<G>)
- <<maybe blown up, enhanced and exaggerated to extremes so I get it!>>,
I'd REALLY appreciate seeing it.
(3) Is the difference in "red" letters/denom. v. "pink" on inlay?
(4) Does the N5129 just say "Reno" and the N5140, "Reno and Lake Tahoe"?

and does the chip shown here appear to be the N5140?
Any help (straightening out/ color-blind testing, or remedial reading WITH comprehension would be appreciated! THANK YOU!)
