I emailed the Brunswick Company and just received a response:
Trade tokens or trade checks were offered by Brunswick to their billiard
room proprietor customers throughout the 30's, 40's. They disappear from
Brunswick product catalogs by 1950.
Some of the catalog descriptions list the composition of the trade checks.
During World War II they were listed as composed of "special red fibre",
and as "not inflammable" and that the dye was not harmed by alcohol or
water. After the War tokens were offered in aluminum.
All of the archival literature we have available lists the denominations
the tokens were available in as: 5 cents, 10 cents and 25 cents "in
merchandise". They were sold to proprietors in lots of 100, 200, 300, 500
or 1000, with the billiard room name and address stamped for free on the
reverse side of the token.
Attached are some catalog shots from that era showing the tokens for sale.
