it was likely removed from some piece of equipment, so test it on the bench and determine if the contacts have been damaged or not. If okay, then take the money and keep it;

You would need a 4-wire meter to measure the exact sub-ohms of the contacts, but a quick check would be to energize the coil and just measure resistance across the contacts.
If it measured more than 1 Ohm then it might be damaged; if it is good then it will be under 1 ohm in the 0.1 region depending upon your meter.
For diy use it may not be as critical that it be in "perfectly new" condition. i never send anything back if they offer a discount to make it right, but that's just me.
