There are two photographs on the University of Bristol's Historical Photographs of China website that the caption associates with the junk on the 1932 Sun Yat-sen silver dollar.

Caption: This photograph of a sea-going, becalmed junk appears to be have been used for engraving the reverse side dies of the 1932 Chinese silver dollar (one yuan). This coin featured a Chinese junk, sailing to the right, with three birds flying above the mast tops. Appearing to the right of the junk's prow is a rising sun. On the obverse side was a portrait of Sun Yat-sen, facing left. The design of the 'Junk Dollar' or 'Sun Yat-sen Dollar' was unpopular, as the rising sun suggested Japan and the three geese, Japanese bombers. The birds and the rising sun were omitted when the coin was minted again in the following years.

The photographs are in the Oliver Hulme Collection. Oliver Hulme (b.1882) worked for the Chinese maritime customs service and later for the China Post Office.

Many thanks to Jamie Carstairs, Senior Digitisation Officer of Special Collections, ASSL at the University of Bristol, for bringing the photographs to my attention.
