Here is the last of my trio of '99s recently acquired. Common below Fine but harder to find in better grades so I'm quite happy with these.
Scott, when you say from 1699 the quality goes downhill I assume you mean quality control, as evidenced by the number of legend errors seen? I've always found the portrait and Britannia dies to be superior to those of the first two issues. The portrait, particularly, is better rendered and stands in bold relief compared with the first which is somewhat flat by comparison.
