A secure enclosure is described which is designed to offer inventory management and tamper detection for the storage and removal of rolled coins and other valuable items. Within the secure enclosure a plurality of shelves are provided. Each shelf may have its own scale for the purpose of weighing the contents supported by its shelf. Each shelf may be designed for the storage of one particular denomination of rolled coin. Monitoring circuitry interfaces with the scales for the purpose of determining the quantity of rolls upon each shelf, and the possibility for an erroneous deposit or removal of rolls supported by a shelf or an improper access to other contents on the shelf. A further approach detects multiple types of rolls of coins utilizing a single scale.
