1930年有利银行伍拾员样票，无编号，棕色，中央为舢板和船隻图案，PMG 65EPQ。情况与该行的贰拾伍员纸钞类似，评级纪录中行钞数目不足4枚，目前能获得未流通品的唯一方法是通过样票及试色样票。编者认为由于同系列纸钞的贰拾伍员名气较大，因此稀缺度一样的“香蕉船”有被低估之嫌，市场价格未能充分反映其收藏价值。 此枚著墨均匀、对比鲜明，纸身硬挺，纹理保留完好，是PMG评级纪录中之亚军分，仅有一枚获评更高分。“香蕉船”设计经典风尚，图案情景交融，堪称没世难忘的珍品，绝对是众多香港纸钞藏家的文化愿景。
Mercantile Bank of India, Hong Kong, specimen $50, 1.1.1930, no serial numbers, brown, sampan and boats at centre,(Pick 238s), PMG 65EPQ. A possibly underrated type in the cataloguers opinion as the $25 of the same series are more commonly talked about. Much like the $25, there are less than 4 issued notes for this type and currently the only way to obtain an uncirculated examples are through specimens and colour trials. PMG census 2nd highest grade, bested by only 1 higher grade example. An impressive piece with its classical design, intricate design, vibrant printing and original paper! Truely a trophy piece in any collection.
