Presuming Don is correct - and I believe he is - this type of token is typical of a promotion in the grocery whereby customers get one of these tokens with every x dollar purchase. The tokens would be accumulated and redeemed for dishes and silverware that would be on display in the store. I recall a local grocery ran that type of event here in the 1970s, except they went the cheaper route and gave tickets rather than metal tokens. Normally, the promotion would go for months at a time, allowing customers to obtain sets of the housewares. If I recall, they allowed people to add cash to the tokens or tickets to make the purchases, especially toward the end of the promotion.
