​My friend picked up this silver medallion thing, what could it be? It has an IBM (or DBM?) logo, a sterling silver stamp, and can open up to some cardboard stored inside. Weighs a few ounces, about the size of my palm

As title describes. My friend and I have been trying to find the context as to why this item exists. Was it a retirement gift or something?
