It depends on how rare they claim them to be. Originial Singer crinkle fishin aren't that common, but they turn up now and then. I have seen lots of refurbished old machine done in crinkle finish, compared to Singer models who started out as crinkle finish. Refurbished finshes isn't quite the same. I think tall the novelty Featherweights fetch a bit extra, both money and attention. Some seek out a special feature and are willing to pay for it; white, cellery, crinkle, centennial badge,... I have to admit, if I found a 201 with the early type chromed plates I would love it, even if my 1950 201 with pin stripe plates are rather stylish too ;- )
