This is what I found on DailyMail:

A beach scavenger found a waxy lump weighing 37 lbs that he believes is valuable whale vomit worth more than half a million pounds.

Surachet Chanchu was walking along the sand in Songkhla, southern Thailand, looking for recyclable waste when he noticed the grey chunk washed ashore on Wednesday morning.

He was struck by its likeness to valuable ambergris, formed in the digestive tracts of whales and a sought-after ingredient in the perfume industry.

The find may be worth £500,000, or over $600,00 USD.
