Certainly, there’s an awful lot of “collectibility” regarding a Telecaster, or the “Nocaster” as the 1951 model was known. If memory serves me correctly, Leo Fender had to give up the name “Broadcaster” because Zenith Televisions had a patent on the name and they didn’t want to share it - I’m pretty sure it was Zenith.
Anyways, for mine, you realistically could get any Fender up until about 1967 or 1968 and they’re all gonna be wonderful. They changed very little in that time - save for some superior electronics and some extra coil windings on the pickups to improve voltage output.
However, Fender historians will be aware that CBS bought the Fender company outright in mid 1965 - but very few changes were noticible in the first 18 months. By 1967 the first “silverface” amps were appearing, and in 1968, the first Telecaster Thinline - that is, a guitar which is very similar in build to Gibson’s ES335 - of which I own 1968 version of both by the way - well, the Thinline showed up in 1968 because Fender was starting to notice shortages in the world wide supply of ash - and a semi-accoustic version of the Telecast allowed them to use far less ash with a solid maple insert running from the neckjoint through the body.
Personally, apart from the sheer joy of being able to say that you own one of the very, very first Telecasters - in my considered opinion there’s very little musical worth in owning one from 1951 as compared to say, one from 1957. Certainly, Larry Carlton speaks glowingly of his 1951 Tele, but nowadays prefers to use his 1968 ES335 because, in his words, overall it’s a more versatile guitar.
As they say - nothing twangs like a Telecaster, but nothing is as versatile as an ES335.
If I was to get a solid body Fender I’d be happy with a circa '64 era one - it was still made entirely by the original Fender owned company and they had changed very little since their introduction - and yet they’re still manageable to buy cost wise.
Just for your reference, I also own (amongst various vintage amps) a genuine '65 Fender Twin Reverb - the real deal blackface monster. Man, what a tone machine - but shit it’s loud. Ear shatteringly loud.
