Found vintage vinyl toy figures in a blue tin

I found a small collection of vintage vinyl action figures this afternoon in a blue tin near the bike racks by Riverside Park in downtown Parkersburg, along Market Street. The tin is about 6 inches square, with a white label that reads 'Retro Heroes,' and inside are six figures about 2 inches tall, some still in their plastic packaging. One figure has a tiny red paint chip on the helmet and a faded sticker reading 'RH-80'. The figures look well cared for, clearly meaningful to someone, and I'd love to help reunite them with their owner here in Parkersburg-Marietta.
