Picked these up today, both apparently silver. Were in a bin labeled “foreign silver," so I don't know what they are or where they're from. Neither of them are in the catalogue. Thank you to whoever can help. (First two and last two are same coins)
Best way to get items identified is to also include some metrics like size and weight.
From typing in the inscription on the obverse of the first item in the search field, you can figure out it is some kind of token or medal for the Holy Year of 1975 under Pope Paul VI.
