A date hidden on the edge
Many owners think they hold an “undated” coin. Neither the obverse nor the reverse shows a year: it appears only on the edge, in raised letters, after the words REPVBBLICA ITALIANA and between two groups of stars. Turn the coin slowly under a lamp; a magnifier helps.
This has a practical consequence: a 1958 coin and a 1995 coin look identical face on. Only the edge separates a circulation piece (1958 to 1967) from a coin taken out of a collector set (1968-1970, then 1980 to 2001).
Set coins have usually never circulated: crisp surfaces, original lustre, sometimes a mirror field in the years when the Rome mint offered that finish. A circulation piece, by contrast, shows a few years of wear in purses and pockets. When the condition is good, check the year too: 1965 and 1967 are the least struck dates, with 3.12 and 2.48 million pieces, against more than 24 million in 1958 and in 1960.
The flags-against-the-wind affair
The project was launched in 1957 by the Treasury minister Giuseppe Medici, who wanted a precious-metal coin to symbolise the newly regained stability of the lira. Chief engraver Pietro Giampaoli tried several reverses (Saint George, David, a ploughman, flowers) before the caravels won the day.
At the end of 1957, a first version marked PROVA (trial) was struck and handed to members of parliament at the close of the legislature. On 10 December, a naval captain pointed out that the pennants at the mastheads blew to the left while the ships were heading right: the flags would be against the wind. Sailors disagreed, some arguing the point of sail was possible close-hauled. The mint chose to correct the design before regular striking: on every circulation coin, from 1958 on, the flags fly in the direction of travel.
The 1957 trial is therefore recognised by three signs: the word PROVA on the reverse, flags pointing left and the date 1957 on the edge, where REPUBBLICA is spelt with a U. Its mintage is disputed: about a thousand pieces as first intended, more than 2,200 according to a Guardia di Finanza inquiry in 2000.
Not to be confused with
The 1961 Unification centenary 500 lire. Same silver and weight, but an entirely different design signed Guido Veroi: a figure of Italy and a four-horse chariot, with 1861 and 1961. Its edge carries an inscription specific to the centenary.
The 1965 Dante 500 lire. Portrait of the poet on the obverse, an allegory of the Divine Comedy on the reverse; the edge celebrates the seventh centenary of his birth. It circulated at the same time as the Caravels.
The bimetallic 500 lire (1982-2001). A smaller coin (25.8 mm, 6.8 g) with a yellow centre and white ring, showing Piazza del Quirinale on the reverse: no silver at all.
The 1957 trial strike. Same bust, same ships, but the word PROVA on the reverse and flags pointing left: see above.

Judging the condition of your coin
835‰ silver wears quickly in a pocket. On the obverse, the most exposed reliefs are the hair and the embroidered garment of the bust: on a heavily circulated coin, these details melt into a smooth mass. The small shields around the rim then lose their inner figures, and finally their outline.
On the reverse, look at the swelling sails of the three ships, the rigging, the flags at the mastheads and the pattern of the waves. On a lightly worn coin the VEROI signature between the waves reads clearly; it vanishes quickly with wear.
The edge matters too: if the lettering is flattened, the date becomes illegible and the coin loses part of its interest. Coins kept for a long time take on a grey or iridescent toning; do not remove it, since cleaning leaves fine scratches and dulls the metal. Finally, check the weight: 11 g for a genuine coin. A clear difference or a dull ring should make you think of a copy, and a numismatist can confirm it.
