I give my children special slips of paper as a reward for good behavior (a "token economy"). They can collect these slips of paper and use them to "buy" rewards such as toys, treats, or fun activities.
Do these reward tokens have the halachic properties of money? For example, are they muktzeh on Shabbos? Could I reward my kids with them on Shabbos? Could they trade them in for prizes on Shabbos? Do they theoretically have a value that makes it possible to use them in any kind of kinyan or redemption?
