Trivial Trivia - taking trivia to new levels

[L Verge]

Just saw a piece of trivia that y'all probably already know, but P.T. Barnum offered Alphonso Donn $20,000 for the clothes Lincoln was wearing when assassinated, but was turned down. I know that Congressman Fred Schwengel was instrumental in getting funding from an American truckers' association back in the 1960s to buy the outfit from Donn's descendants. Does anyone know how much was paid at that time?
