Neat finds, and good luck with the lottery!
The design for these pocket pieces is not copyrighted, so a number of companies have made them in various metals with only minor variations in design. For many years they have been used in direct mail promotions by the Catholic Charities organisation in their yearly appeal for donations and also by their sister organisation, the Catholic Relief Services (founded in 1943 as the War Relief Services in Baltimore, Maryland but changing its name to CRS in 1955).
The tokens are issued as a symbol of peace, community, and love as well as being tokens of appreciation for donations or participation in CRS-related charity work.
