Australian Pre-Decimal Souvenir Set of Commemorative & Regular Issue Florins 4 Coin SetPre decimal commemorative florins (two shilling coins) were issued on only four occasions: in 1927, 1934 35, 1951 and 1954. The 1934 35 florin was issued at a premium over face value to commemorate the centenary of Victoria and Melbourne. With a low mintage of 54,000, the 1934 35 commemorative florin is now quite rare and is therefore not included in this souvenir coin set.
