This is a 50mm diameter coin slot and backing plate which provides for mounting a small IR sensor to detect the insertion of a coin.
In production I pair a nice looking chrome slot from Aliexpresshttps://www.aliexpress.com/item/10-pcs-Zinc-Alloy-Coin-Slot-Round-Coin-Entrance-Door-for-Coin-Acceptor-Arcade-Games-Parts/32782156047.html?spm=a2g0s.9042311.0.0.dlHLNu
with the backing plate and this sensor:https://www.amazon.com/gp/product/B008DG96NU/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
The sensor wiring is tricky and requires 2 resistors. I've used this setup successfully with RPi and Arduino button detection libraries but it takes some playing.
