The Perth mint series is relatively easy to complete with all dates available in mint state for close to bullion value. The 1929 is the scarcest to acquire in mint state while the 1930 and 1931 are readily available from MS62 to MS64. The 1931 is available with both a matte and brilliant finish. While the matte finish is slightly scarcer, the brilliant finish tends to sell higher due to a more attractive appearance. The matte finish appears to be the only type to turn up in MS65 or higher with the brilliant finish piece usually being softly struck up.

Type set collectors will be challenged if seeking the series in higher mint state grades.
