Anything that old may be valuable but Colonial of Zeeland has made many clocks over the years. They not in business as such now. The clock works were made by a different Company - many times (or most times) a German manufacturer. I have three colonial grandfather clocks and paid 1800 new for a Henry Ford Museum reproduction about 35 years ago and 2100 for another repro of the same kind (Joseph Doll Clock) this year. and about 1500 last year for a 40+ year old glass front different model - so it depends on what you mean by valuable. Does it run and are all part there?
