Watch List notes:

AUSTRALIA'S 150TH ANNIVERSARY, 1788-1938, in silver (57mm) (C.1938/7), by Amor, edge marked St.Sil and also inscribed, 'MS1'. Uncirculated and very scarce in silver.

Usually struck in silvered bronze, this medal is possibly a specimen strike for the Ron Byatt Collection, hence it is marked 'MS1' (minting (?) specimen 1).
