By "soldered-in" crystal earphone are you referring to an earphone permanently-attached rather than plugged in? If this is the case, (and I'm pretty sure it is) it's a rather rare radio. The design eliminated the audio output stage, thus eliminating a tube and the speaker...with the side benefit of smaller size and a bit less battery drain. Google the m31galaxy of transistor radios and you'll find a picture of a Copit PC-200...could well be the radio you have. Though it won't fund a college education, it should still fetch a tidy sum.
