1957 TV Blue Book values.

[Eric H]

I just received a "NARDA" TV Trade-in Blue Book for 1957, it's interesting to see what some of our most prized sets were worth as a trade in back then.

1946 621TS $1.81
1946 630TS $2.82
1954 CT100 $112.64

Dumont trade in values held up pretty well, surprisingly the "Chatham" doghouse set was the least valuable.

1947 Chatham $8.11
1949 Manchu $70.93
1951 Royal Sovereign $98.22

1947 VT-71 $2.84, in blond $2.99, .15c difference, how did they calculate that!

Funny thing is all the Electrostatic 7" sets have a higher trade in than the 7" 621, even though they are of similar age and the 621 is a much better set electronically.
I suppose a 621 just seemed hopelessly old fashioned and outdated by 1957, probably downright embarrassing to have in the house.
