These are tokens, also called jetons, used in games and gambling during (what else?) the good old days. Dates range from 1787 to 1800, although they were probably produced well after that time as well. Patterns are many, but with a similar theme. They are made of brass.
There is an excellent write-up on these intriguing tokens over at Chard, and CoinQuest thanks Chard for use of their photo.
Singly these usually sell with catalog values as follows:
worn: less than $1 US dollar approximate catalog value
average circulated: $1
well preserved: $3
fully uncirculated: $6
They are interesting pieces, make great conversation, but are not worth very much.
