About This Phone
An early model coin telephone — a 'post-pay' model, which meant that the operator would make the connection for you and then ask you to deposit the coins. The 23D was often a "three-slot" design (nickels, dimes, and quarters). It is well-known for its distinct mechanical signals: Nickel: One bell ring. Dime: Two bell rings. Quarter: A deep gong sound. This 23D Gray Pay Station is equipped with a Canadian coin gauge designed to accommodate both the smaller Canadian silver 5-cent coins and the larger Canadian nickel 5-cent coins.
