Denomination: Silver stater.
Mint: Kroton.
Date: ca. 480 to 420 BC.
Size: 19.0 x 20.0 mm Weight: 7.73 grams.
Reference: Sear-466 variety.  SNG ANS 314
Grade: VF.
Obverse: Delphic tripod with three handles, with a stork to the left, with an inscription to the right naming the city as "KAPPA" RO (I cannot show a Greek letter Kappa on the fonts available here).

Denomination: silver tetradrachm.
Mint: Syracuse.
Date: Time of Gelon, 485 to 479 BC.
Size: 22.9 x 24.3 mm  Weight: 17.2 grams.
Reference: Sear-913.
Grade: gVF to aXF, with good metal and a slightly larger than average flan (about 1 mm larger) which allows for nearly the entire obverse design to be visible (at least more than you usually get).  There is a very small corrosiion spot on the horse's shoulder, but it is very minor.
Obverse: Quadriga driven right by a male charioteer holding a goad, with a small figure of Nike flying above.
Reverse: Head of Artemis-Arethusa right, with four dolphines around, with  SURAKOSION to the right and below.

Taras is in Calabria in southern Italy, and is also known as Tarentum.  This particular coin is from what is known as the Campano-Tarentin type, because the obverse is based on the coins of Neapolis in Campania, while the reverse is a Taras type, with an ethnic that states the coin was issued from Taras.  This suggest that it was struck during a period of alliance between the two cities.  A search of the first 500 coins of Taras in coin archieves did not turn up a single one of these, suggesting it must be a fairly rare type.
Denomination: Silver didrachm (sometimes called a Nomos).
Date: 302 to 281 BC.
Size: 18.9 x 19.9 mm, Weight:  7.02 grams. 
Reference: Sear-366 variety.  Vlasto #1031 to 1035.
Grade: VF but slightly off-centre. Nice old toning.
Obverse: Head of a Nymph left.
Reverse: Youth seated on a horse standing right, holding a wreath over the horse's head, with a rhyton below the horse, and a dolphin in front, with TA behind the rider.

For reasons I do not understand, it has become fashionable to call this coin denomination of nomos.   The Greek word "nomos" appears to simply mean "acceptable currency" and is more an accounting term than the name of a specific coin type. 

Denomination: Silver stater (nomos).
Mint: Kaulonia.
Date: ca. 475 to 425 BC.
Size: 19.3 x 20.8 mm Weight: 8.08 grams.
Reference: Sear-462. HN Italy 2046.
Grade: gVF with a nice strike and reasonably well-centred for the issue.
Obverse: Apollo walking right holding a laurel-branch, with a small figure standing on his arm (the small figure is not visible), with a small stag standing in the right field, with a retrograde KAVL to the left of Apollo.
There are many small raised marks in the obverse field, which had to have been on the die and are intentional (and occur on many coins of this type).
Reverse: A stag standing right with a sapling growing in the right field, with a retrograde KAVL above the stag's back.

This type is rather odd in that the ethnic for the city occurs on both the obverse and reverse dies, but for some reason the early coins of this city often show this.
