APPRAISER: What were they asking for it at the yard sale?
GUEST: They were asking ten cents for it.
APPRAISER: And you paid the whole ten cents.
GUEST: I paid the whole ten cents.
APPRAISER: All right. There are a lot of oyster plates around. Most of them, to be honest, aren't of any great value. But when you see this mark, "UPW," it means it was made by a company called the Union Porcelain Works. I think in a good auction today, this is going to bring about $300, maybe $350.
GUEST: That's great.
APPRAISER: Now, if it didn't have this mark, it would be worth maybe $20 or $30.
