Because i have a Rare Downies Prestige Gold Sovereign Collection of quality Sovereigns, All Perth mint Hallmarked from 1901 to 1920. These are AU to MS63 coins and includes the better dates Like the 1911, 1904, 1902, 1913, 1901. CV on this is huge and Perth sovereigns are hard to find in decent condition and Downies would be asking close to $20k for these 20 quality sovereigns
they are not graded by a third party grading company but they are compiled by downies because they are high grade sovereigns and being Perth sovereigns they are rarer still.
