coke mantel style clock

Have had this clock about 20 years. when dusted it looks brand new and even works. I used to keep it plugged in and on display but now it sits above my work bench. i've looked for a value but never seem to find the exact one to compare it to. I've seen the one with "pause" where the clock face is but none like the one I have. The date inside on the motor says 4/55 any body have any idea what the value is ???
