Jews by the time of Jesus were very diverse just as they are today. Even in Judea itself you would find very different opinions on how "the law" (Halacha) should be interpreted. Most would probably find it silly and impractical to not use Roman coins. The point of Matthew 22:15-22 may be that. The Pharisee hands him a coin with the image of the emperor on it and Jesus reminds him that "Hey, you shouldn't be touching this at all. You hypocrite!"
