Le leghe di ottone, rame e altro rame possono essere sottoposte a nichelatura che conferisce loro un rivestimento color argento resistente e brillante che non è soggetto ad annerimento.
I gettoni nichelati hanno lo stesso peso e la stessa firma elettromagnetica di quelli non placcati per cui è possibile mischiare gettoni placcati e non placcati senza dover riprogrammare il convalidatore di monete.
In teoria è possibile nichelare qualsiasi lega ma la nichelatura viene effettuata principalmente su leghe non di color argento tra cui:
Ottone 63/37
Ottone 70/30
Ottone 85/15
Rame
