Holographic Commemorative Bitcoin, designed and manufactured in America. Inspired by the original Casascius coin, this item is an eye-catching decoration and a great gift for any crypto enthusiast.

The rear of the coin will reflect the full spectrum ("rainbow" colors) under direct light, including direct sunlight. Under diffuse light, it will simply appear gold, and features will be difficult to make out. To show off the colors, display the coin under one or two directed light sources, or shine a flashlight onto it (such as your phone's).

Materials: Copper coin with silver cladding and gold plating. Polyester diffraction grating with gold sputter coat (“gold foil”).

Answers to anticipated questions

Is this a real Bitcoin?
This coin does not have monetary value in any currency; it does not carry Bitcoin and cannot be loaded to carry Bitcoin. While theoretically a private key could be placed under the security sticker, this has not been done to avoid regulation issues with the SEC.

What makes the coin holographic?
When minted, the back of the coin is blank, struck with a blank polished die. A holographic label is applied at the mint before placing the coin in its capsule. This label is a sheet of “gold foil” (elemental gold on polyester) which has been stamped with a diffraction grating.

Why not stamp the coin instead?
The gold plating is applied after the coin is struck, and once the coin is plated, it cannot simply be returned to the press for hologram application. The diffraction grating on the coin is thinner than the gold, so applying the gold on top of it would dampen the holographic effect.
