A revival / new instance of this old story seems much more plausible than these people finding literally thousands of Euro coins in cars sent for scrap, and taking those coins to France (how many Euro coins can you fit in your luggage? how can you get them through Customs? Why wouldn't you exchange or deposit them at home?)
The old story begins thusly:
Precious Metal: Scrapped Euro Coin Scam Costs Bundesbank Millions
German prosecutors have uncovered a 6 million euro scam involving reconstituted euro coins that had been sold to China as scrap metal. One and two euro coins were then brought back to Germany, some via Lufthansa airline employees, and traded in at the central bank.
An alleged scam has been discovered, involving the reconstruction of previously "destroyed" euro coins, according to German authorities
German investigators say they have discovered a massive scandal involving the reintroduction of euro coins that had been taken out of circulation and sold as scrap to China. The scheme, said to have cost Germany's Central Bank €6 million ($8.5 million), involved airline employees -- including Lufthansa flight attendants.
