20 Euros Natures de France 'Le Chêne'

The "Natures de France" series launched by the Monnaie de Paris draws on a long French tradition of associating the oak specifically with rural permanence and republican virtue — the tree appears in civic iconography stretching back through the Third Republic. The 2020 oak issue was struck using a selective gold-plating technique on certain relief elements, a finishing method the Paris mint has increasingly deployed to differentiate collector silver from generic bullion.

Mintage for the series was tightly capped, as has been standard practice for Monnaie de Paris themed naturalist issues since the mid-2010s.
