Egyptian Cat Bust: $80,000

This ancient feline was almost thrown away at a yard sale in Cornwall, southern England. It’s 2,500 years old and originated in Egypt (why would you want to throw this gem away?). Once the yard sale ended it was left over but the owners did end up throwing it away.
Fortunately, someone got ahold of the artifact dating back to at least 500 B.C. and it was authenticated by an Egyptian expert at The British Museum. It was auctioned in London back in 2015 and sold for $20,000. A London dealer would later buy it for $80,000.
