The 1903 Chihli dollar (Y73.1) is much scarcer than its sister Chinese silver dollar, the famous Y73.2 made in 1908 (see related articles), but it is also somewhat less studied. Currently, only the variety with a full-stop after PEIYANG is acknowledged by grading agencies. There exists actually much more interesting and rare varieties, which are actively sought after in China. Similarly to the 1908 Chihli dollar, this 1903 dragon coin has been minted in several version with different typography for the date. The most dramatic is the 艺术字 (artistic font):
Besides the roman numerals, another device to examine carefully is the 錢 character on the reverse of the coin. On the full-stop after PEI YANG coins, the 金 part (radical) on the left of the 錢 character has been calligraphied in four different ways:
The picture 1 is representative of what you see on 90% of Y73.1 dragon dollars: this is the most common variety. The calligraphy shown on picture 3 is called 中折金 and is much scarcer: both side strokes of the 金 radical are curved in a very noticeable way. Even more rare, the 挑金 variety (picture 2) is easily identified by its incurved left stroke. The rarest of all the varieties is the 双折金, with characteristic vigorous tapered strokes on the side and bottom (see picture 4 and details).
If like me you collect Pei Yang 29th year Chinese silver dollars, be on the lookout for these rare varieties: while they enjoy some popularity in China, most collectors abroad are still unaware of them, so there is good opportunities around.
