It comes from Dollarhyde, anyway. Hyde referred to a trapper who sold pelts, or hides. Perhaps "dollar" is a type of animal in Old English that could be trapped, or else it is probably and adjective describing the trapper (like "good trapper" or "tough trapper" or whatever).
I don't have my Old English studies with me now, or I'd look it up.

'Dollarhide comes form Delahyde or De la Hyde, meaning "of the land" and likely came to the British Isles from Normandy with William the Conqueror.' -from the Dollarhide family page on http://www.murrah.com/gen/dolrhide.htm
