I've only paid dollars for mine. But my dad has done a bit of trading. Back in the sixties, he would go around the farms of the local area, and pick up unwanted cars, especially Model A's. There was one that was in a shed, but the owner didn't want to get rid of it because it was a good source of nuts and bolts for farm repairs. Through out the next few weeks, dad requisitioned nuts and bolts of various sizes from his work place. When he thought he had a big enough supply, went back to the farmer, and offered to swap the nuts and bolts for the A. A swap was made.
