I worked on creating a spreadsheet that shows different values for most of the general gather-able items in game. It lists in game item value, how many can stack together, the stack value, how much you can sell the stack at most vendors and a separate value for tool vendors, shrine points values, and a suggested auction price in order to 'break even' with what you could have received from the tool vendor. It's a work in progress, comments and suggestions are welcome! I hope people find this to be a valuable reference.
