Antiques Roadshow - Season 16

A signed note from Mother Teresa to a wood-carver; a custom model 1894 Winchester rifle; and a collection of late 17th/early 18th-century Chinese libation cups - grabbing the number one spot on the list of all-time highest value ROADSHOW appraisals.

Signed Ty Cobb memorabilia dating back to the early 1950s; an original Rosemary's Baby drawing by art designer Clem Hall; and a 1919 oil painting by Norman Rockwell.

Correspondence between Cole Porter and actor Monty Woolley; a finely knotted circa 1920 silk Kashan rug; and one of the best flea market finds of all time: a 17th-century Chinese rhinoceros horn cup, purchased for $1 and valued at $350,000 to $450,000!.

A 19th-century Fiji split whale's tooth necklace; Andy Warhol's 1966 artist's proof of a print of Jacqueline Kennedy; and a 1937 first edition copy of The Hobbit, with original dust jacket and author J.R.R. Tolkien's signature.

A decorative egg with a Faberge mark that may not be all that it seems; a 1787 land grant signed by Benjamin Franklin; and a New York Chippendale corner chair, circa 1760.

A questionable George Elmslie chair that, if authentic, could fetch $50,000; a 1900 McKinley-Roosevelt poster discovered at a flea market; and a 1976 fancy intense yellow diamond ring.
