Here is the full page of evidence 2:


▲ 精刻海若湯先生校訂音釋五侯鯖字海（明刊本）卷3 folio 40a, 言部/15畫

In the full page we can also find ⿰言錦 (in the blue rectangle)：「稅說二音，䜛也」. ⿰言錦 might be a variant of ⿰金䛲.

Here are some new evidences:


▲ 泰和五音新改並類聚四聲篇（金刊元修本）卷3 folio 8a, 言部/15畫, quotes 搜真玉鏡.


▲ 明神宗顯皇帝實錄（紅格鈔本）卷584 folio 7a （萬曆47七月七）


▲ 明神宗實錄校勘記（中央研究院歷史語言研究所）p2722 (Also shows ⿰金諱/𲇠(WS2017-04454))


▲ 明熹宗哲皇帝實錄（紅格鈔本）卷72 folio 11b （天啓6六月十一）

From 明實錄 evidences, we can conclude that 𲇠/⿰金諱 is misprint of ⿰金䛲.
