Tenshodo Passenger Cars-Collectors Items?

[Isambard]

Years ago I inherited a number of Tenshodo passenger cars that were purchased around 1959 and which had only limited running. They've been sitting on a shelf in their original boxes for the last 40 years. I have not bothered to see how they run as the Grizzly Northern is a 1930's steam era CPR subsidiary. It would be interesting to know whether they are worthy collector's items. Here's a list:
12 Union Pacific “City of Los Angeles”, flush sided, yellow body, grey roof cars:
Baggage/Day Coach w. seating, lighting installed. Paint chipping on roof
Day Coach w. seating, lighting (uninstalled)
Vista Dome Observation w. seating, lighting installed
