This chart is about sample slab values, slabs that have been sold and for what price. It is just a guide nothing more, but you can see how much  samples have sold for. . Even the same samples are listed as for the most part all sold for different prices. If you are bidding on a sample in the list and there is more than one example you can get and average of what you think is a fair price. As I am doing this by TPG there will be differences in the dates as I am trying to group them when possible by Denomination as per the TPG.

This is just the beginning of the value charts that will be posted. It will take time to list all the sample slabs that have sold in the last few months. It will also be updated as time permits, hope it helps.
