Kroton, Bruttium, AR Nomos, ca 480 BC. 7.91 g. 

Tripod with volutes; dolphin to left.
Incuse eagle flying left, wing and tail feathers clearly 
defined. 

Attianese -; SNG ANS -; HN Italy -. 
Unpublished in the standard references. ($2000)
A new type in the Kroton series, apparently a transitional issue between the "medium" and "dumpy" incuse issues.
The dolphin symbol appears as a subsidiary symbol on HN 2089 
and HN 2100
On this coin, as well as the double tripod issues with dolphin, that border is plain on all known specimens (eg Dewing 598; Fitzwilliam 748, Weber 999-1000). 
Jameson 418 appears to have a radiate border, but it was hand-engraved at a later date.
