これら ('these') is the plural form of これ ('this'), built with the productive plural suffix ~ら. The same pattern gives それら ('those'), あれら ('those over there'), 我ら ('we'), 彼ら ('they'). ~ら is more literary or formal than ~たち for plural pronouns; in everyday speech the distinction is often left unmarked. コイン is a katakana loanword from English; the native term 硬貨 (こうか, 'hard money = coin') is more formal/written.
