On the hip scale, not that high. 700c or 27"? Stainless, chrome or cad plated spokes? 4x, 3x? 120mm? 126mm? all those factors can effect value. On the plus side if 700c, most of the current tires will mount very well with the ability to hold the stated pressure. Straight lever quick releases are more desireable than the later curved. In that period most likely 36 hole, if less than worth more.
