1974 Challenger Bumpers – Scrap Them??

Replaced the bumpers on my 74 Challenger with the 71 version. Cleaning up my shop this week and headed to the scrap yard tomorrow with some brake drums, rotors, etc. … Questioning whether I should take the bumpers along and get my penny/pound or whatever scrap metal is going for these days, or hang on to them and try to sell them. Seems like they would be a tough sell considering the cost to ship these boat anchors. Any thoughts? Any market for these things?

Thanks
