The Irish international coin fair opened at the RDS in Dublin today.
Coins, bank notes, stamps, medals and other collectables will be traded and exhibited at the two-day event in Serpentine Hall.
The fair will host collectors from Ireland, the US, France and Germany.
Items of interest for collectors at the moment include good quality high value bank notes and the 20 pence coin from 1985, which was specially issued for the calibration of telephone boxes.
Organisers say as the 100th anniversary of the 1916 Rising approaches, there is mounting interest in memorabilia from the period.
The Central Bank will be represented among the more than 26 stands at the fair.
A free valuation service will be available for members of the public on Sunday.
Admission is €3 and the exhibition opens from 11am to 6pm.
