There a lot of questions asked about coins.. First, what are the exact dimensions of a coin (weight, diameter and thickness).. Second, what is the coin made up of (metallic content).. Third, what is the Obverse and the Reverse sides of the coin.. Fourth, what is the actual mintage.. Fifth, when was the coin released (one Phil. coin was issued ahead of the date on the coin).. and other more questions.. when I joined the groups, I thought that I would get the answers, but most of the people are not that well informed or do not care .. somebody or any responsible group should ask the BSP to give the official data or facts..
