Niether US nor Canadian quarters have ever been made of zinc. Please check your coin again and post a new, separate question with its date and country of origin.

US quarters were made of 905 silver and 10% copper until 1964. Since they they've been made of cupronickel outer layers bonded to a pure copper core.

Canadian quarters were made of 80% silver, then 50% silver, followed by pure nickel and finally plated steel
