I have somewhere north of one hundred landscape blocks that were removed from home planting areas that we no longer wanted. All of the blocks are wedge shaped as shown in the attached pictures. There are two sizes. The heavier ones are just over four inches thick and just over eleven inches at the widest part of the wedge. The thinner stones are just over two inches thick and are the same width as the heavier ones. A couple of things to note: (1) with one or two exceeptions, these stones are all intact. A couple may have been scored and split to accommodate the installation. (2) These blocks may not look all that great, but that's because they are dirty/muddy. I power washed one to see how well it cleaned up and it looked good. I should have had the kids that moved these for me take a count of each size. I didn't, so my best guess is that about two thirds of them are the thicker heavier ones. 

One stipulation: Anyone that wants these has to take them ALL. Sorry, but I have to be firm on this. If this won't work, I'm just going to contact a junk removal service to get rid of them.
