hotside
Hotside refers to the side of a coin that is facing up or is in contact with a heated surface, such as a coin operated machine or a hot plate. The term is commonly used in the context of vending machines, slot machines, and other coin-operated devices. When a coin is inserted into a machine, it typically lands on the hotside, which is the side that is in contact with the heated surface of the coin acceptor. This heating process helps to prevent the coin from sticking to the machine and also aids in the detection of counterfeit coins. The hotside is also known as the "top side" or "upper side" of the coin. In some cases, the hotside may be marked with a specific symbol or design to indicate its orientation. The opposite side of the coin is referred to as the "coldside" or "bottom side."
