Nuggetin Pokémon Polished Crystal

A solid gold nugget. Sells for a high price. Nugget is purely a sellable item with no battle use. If you take it to any Poké Mart, you can sell it for cash. You'll find Nuggets as hidden items, battle prizes, and occasionally from certain NPCs. Team Rocket famously gives one out on Nugget Bridge. There's no reason to hold onto these unless you're collecting everything.
