Precious Rocks

These were found by my very young child, and now would like to sell them! He would like to buy some things, and is looking to sell his findings. The childs description is as follows: The smallest rock looks like red clay, and it is really cool! This was found in the rocks by four other rocks. The black and white rock looks like coal. The pebbles are like iron. This was located on the walkway to the library. The big one look like normal clay, the crack in it means it is probably cracked. You could probably make into clay. This was located in the grass. PARENTAL DISCLAIMER: These are only precious to him! We are teaching him the entrepreneurial spirit, and even telling him these are not of value, they are to him. Hence the listing! Thank you! H1133
