A collectable mounting device is configurable to a wall-mounted configuration, and a horizontal support surface (or shelf) mounted configuration. In the wall-mounted configuration, support members are secured together via a fastener through the adjustment slots such that support channels extend in the same direction to support the collectable on a wall. In the shelf-mounted configuration, the support members are fastened together such that the support channels extend in opposite directions, and a tensioning member is inserted between the support members in opposed tensioning member receiving slots to flex the support members away from each other. A packaging method includes stacking the support members and tensioning member to align holes therein; wrapping a label around the stacked support members and tensioning member to align holes in the label and holes in the support members and tensioning member; and inserting a fastener through the aligned holes.
