of blue. And the sheets of the 4d., in like manner, each contained a
1d, which, when the 4d. was printed in its proper colour of blue, was
also printed in blue instead of red, the proper colour. These errors
are very scarce, especially in an unused condition. The 1d., blue, is
the rarer of the two, and is worth about £70 used; it is not known
unused.

Tuscany, 1860, 3 lire.--In the early days of stamp production high
values, such as we are now accustomed to get from most countries, were
very rarely issued. For nearly thirty years Great Britain was content
with a shilling stamp as its highest value. In 1860 the Provisional
Government of Tuscany issued a stamp of 3 lire, for which there seems
to have been very little use. It represented but two shillings and
sixpence of English money, but it is nevertheless one of the great
rarities to-day, especially in an unused condition. Used copies are
worth about £65, and unused about £120.

Transvaal, 1878. _Error_ "Transvral."--This error occurred once in
each sheet of eighty of the 1d., red on blue, of the first British
Occupation. It was evidently discovered before a second lot was
required, as it does not recur in the next printing of 1d., red on
orange. It is a very rare stamp. Used it is worth about £50, but
unused it is one of the great rarities, and has changed hands at about
£150.
