Italy #1 presents a number of options. Scott starts with #17, the 1c bistre SG1,
priced at £4,500 and £130. It is actually Italian State Sardinia's Sc11 (SG40),
with added perforations. The Sardinia (unperforated) stamps catalogues at £3 /
£5. Another stamp of the first Italian issue, of the same design but more
reasonably priced is the 20c blue Sc19 SG2a at £4.25 / £14.
