John F. Kennedy is about to make America wet all over again, 'cause his original swim trunks, jackets and other family items are up for auction ... starting at just a buck!
Guernsey's auction house is selling off some of JFK's personal items in October to commemorate what would have been the late Prez's 100th birthday -- even though he was born in May.
Some of the items being auctioned off include 3 of Jack's OG swim trunks, a couple of his coats, his U.S. flight jacket, his old rocking chair ... and even his kids' toothbrushes, bristles and all.
There are some Jackie O items up for grabs as well, such as her perfumes, belt, and one of her black lace mantillas -- which she wore to Robert Kennedy's funeral.
All the stuff is starting at a bid of just one dollar ... but something tells us it'll go for A LOT more.
Oh, and happy (belated) birthday, Mr. President.
