The Karpinski Coin Chest is primarily constructed of walnut with mahogany side panels. It features a custom inlay and the interior is lined with crushed velvet. The device allows for the instant appearance (or reappearance) of up to four half dollar sized coins. The mechanism is fully controllable by the performer in terms of the order, quantity, and timing of the firing. The Coin Chest routine requires the disappearance of up to four coins; this can be accomplished with any sleight of hand variation, or by using the Karpinski Coin Stand.
