Gold-plated Bitcoin coins are commemorative, non-monetary collectibles designed to resemble the Bitcoin logo or concept. They are typically made from materials like zinc alloy or brass, coated with 24K gold plating, and often come in protective cases. These coins have no actual cryptocurrency value and are marketed as novelty items, gifts, or display pieces for crypto enthusiasts. They vary in size (usually 38-40mm in diameter, 3mm thick, ~30g), with designs featuring the Bitcoin “B” symbol, mining imagery, or blockchain themes. Prices range from $5-$20 for basic versions to $90+ for premium 1 oz .9999 fine gold rounds, like those from APMEX. Some sellers, like Etsy or Amazon, offer sets with multiple crypto-themed coins (e.g., Ethereum, Dogecoin). Customer reviews praise their appearance, weight, and detail but note issues like flaking gold or cracked cases with heavy use.
