I watch Antique Roadshow from time to time, and some of the nostalgia stuff is incredibly ugly. The experts fawn all over it and nothing that has a high market value is ever called "ugly". Of course, they have a lot of cool-looking stuff as well.
I like to collect small carvings, souvenirs from before when they were all made in the Orient. I have a couple of pewter Viking ships from Norway and a rigged three master someone made as a souvenir in the Gaspé peninsula. I only buy what looks interesting to me, and I never pay a lot. The latest was a handcarved statue of Paraguayan president Francisco Solano López, who declared a war on Brazil, Argentina and Uruguay and fought for the next four years, until 1871, when they were down to using wooden lances, slingshots and bows and arrows. His dying words were "Yo muero con mi patria." I die with my country. Strangely, he is considered a great hero and is the most prominent face on the money.
Paraguay continued to exist, because, like Uruguay, Argentina and Brazil both wanted to take over and neither wanted to fight a war over them.
Eventually, Billy Beer will be a collector item. If you had Andrew Jackson's jockstrap, Jefferson Davis's spitoon, or Alexander Hamilton's truss, those would also be "collectible" of immense value to a few wealthy collectors.
I once heard a tale of some Mexican in Chihuahua who offered a tourist a unique collection: the three skulls of Pancho Villa. One when he was a child, another when he was a young man, and the last one, with bullet holes, from when he was assassinated. It would be fun to bring those to the Antiques Roadshow.
