The AMI F-6463 Coin Slug Cup and Door Assembly is shown in the parts catalogs for the H model, the I models, the J models, the K models,
as well as the Continental, Lyric, Continental 2, JAL, JELO, JBM, JAN and JAO.
In short it appears that it is used in all models from 1957 thru at least 1966 and perhaps later.
The casting itself is marked H-1861 but when the moving door is added to the part it becomes part number H-6463 (or 201-0463 on the newer models).
This one, which is marked H-1861, does not have the moving door so it is lighter in weight and can be shipped cheaper than the F-6463.
