Hi there. I am buying largish amounts of both of the items for my project on SMP8. I will pay 2 rupees per piece of mossy cobble (found in dungeons) and 5 r per two pieces of mossy bricks. If you have cracked or chiselled brick, I may buy some of those, but you have to offer me the price. I may not be buying these for long, so sell them while you can!
