Is the Stardust a 50¢ chip? If so, It could be TCR #N9150 with a "U" value code ($400-$449) in Very good condition

The Tahoe Biltmore $100 looks like TCR #N9200, "M" ($100-$124) in very good condition

The Sahara Tahoe appears to be TCR #N7808 "D' ($10-$14) in New condition

Joby's Monte Carlo, if it has no denomination, is probably TCR #N7898 and is (*N) in very good condition (*N is $125-$149, but the estimated price wasn't based on actual sales....as I understand it)

nice find
