This is a rare Pokémon Gold and Silver Double-Sided Coin measuring approximately 2.5" across. This was a promotional item and was never available in stores. The "Gold Version" side features Ho-Oh and the "Silver Version" side features Lugia. The edging of the coin is gold. The coin weighs a few ounces. The coin has never been taken out of the packaging, and any "markings" seen in these photos are only on the plastic bag, not on the actual coin.
