All of the stamps of this issue are scarce to rare, and worthy of consideration as investments. Five of the stamps (Scott #2, 4, 6, 7, and 9) are somewhat pricey, and the best way to purchase them is probably as used VF-appearing seconds with minor faults such as shallow thins or unobtrusive creases, if such can be had for 10% to 15% of catalog value. Should there be any doubt as to authenticity, insist on making the purchase conditional on obtaining expertization. There are some fairly convincing forgeries of this issue, especially by Sperati.
