Betsy Soule made the vase in the 1970s.
Alvin Barr was ecstatic when he was told by Antiques Roadshow that a vase he bought at an estate sale for just $300 was worth as much as $50,000.
But his joy was short-lived.

The handmade piece, covered in straw and chicken droppings when Barr bought it, turned out to be a high school art project made in 1973 by Betsy Soule in Oregon.
The rather large and homely pot was initially identified as a late 19th-century or early 20th-century piece.
But Soule contacted the series after a friend messaged her that her high school creation was on Antiques Roadshow.

The show has since revalued the vase at $3,000 to $5,000.
Still, not bad for a high school art project.
