Any person in possession of a damaged or defective coin may apply to a credit institution, present it directly in a branch of the Banco de España, or send it to the Coin National Analysis Centre.
Coins that have been altered through an industrial or mechanical process will not be exchanged.
As for banknotes, damaged or defective coins must be subjected to expert analysis, for which technical collaboration is requested from the laboratory of the Spanish public printing works, where the coins are minted.
