An interface apparatus for identical and non-compatible coin holders that enables them to be vertically stacked one atop another, with the interface therebetween, and oriented such that their certificates of authenticity face the same direction. The subject interface apparatus is comprised of a substantially rectangular planar plate having irregular contoured front and back surfaces designed for mating engagement with NGC and PCGS coin cases to facilitate stacking thereof. The apparatus optionally includes voids or "windows" sized, shaped and located to enable viewing of coins and certificates disposed within the cases when mounted thereon.
