If your cards are good, you won't be stuck. T206 cards are the most popular prewar cards, and there will always be a demand for them.
Personally, mine are in SGC holders, but that's because I like a uniform display. They also look great in no plastic at all, in binder pages or in a stack. When it comes time for you to re-sell, if it ever does, there will be buyers.
