New 100- and 200-euro bank notes entered circulation on Tuesday, completing the European Central Bank’s overhaul of paper money to make it easier to handle and more counterfeit-resistant.

The new notes — worth about $112 and $224 — have a shinier finish and more security features, and are more durable than their predecessors, the central bank said. They are also vegan friendly, unlike the polymer bills released by the Bank of England in 2016 and 2017.

A spokeswoman for the European Central Bank, which oversees the currency in the 19 European Union member countries that have adopted it, said that there was no evidence of any animal-based products in the bills’ raw materials.

“The paper we use in euro bank notes is made of 100 percent cotton fiber,” she said, adding, “The euro system is strongly committed to maintaining and improving the sustainability of the euro bank notes and the raw materials used.”
