Heres another idea for promotion. Theres a saying that "a penny saved is a penny earned". I heard this all the time when I was growing up. Simply promote CENT as a good savings tool for children. Persuade parents to save money now for their children with CENTS.
This is a good idea. A school teacher friend of ours thought about using them in her classroom.
I'm not certain about the educational aspects due to the slogan in the logo, "AD DIVITEM INTRARE SPOLIA".
Perhaps, "IN NUMBERS WE TRUST" would be better than "TO ENTER THE SPOILS". It may be hard for kids to become enthusiastic about saving with a slogan like that.
