The evidence is published in 2006, however, ⿰金朐 is not attested in earlier historical evidences, here a chronological list:


▲ 《清世祖實錄》juan 30 folio 24b gives ⿲金目勾, which can be considered as a variant of 𨪵


▲ 《八旗通志初集》（清乾隆刊本）juan 138 gives ⿲金目勽, corrupted form of ⿲金目勾.


▲ 《東華錄》（清光緒石印本）順治 juan 2 gives 𨪵


▲ 《清史稿（1927）》juan 4 folio 14b also gives 𨪵.

And here is 𨪵 from 《漢語大字典》p. 4567, which also quotes 《清史稿》:
𨪵：人名用字。《清史稿•世祖紀一》：「乙未，朱聿釗弟聿鐭僭號紹武，據廣州，佟養甲、李成棟率師討之，斬（朱）聿鐭及……鉅野王壽𨪵。」, apparently 朱壽𨪵 in the evidences above and 朱壽⿰金朐 in 《南明史》are the same person.

Since 《南明史》, published by 中華書局 in 2006, is compiled from 錢海岳's manuscript, and 目 is easily confusable with 月 in handwritten text. I think 錢海岳 was meant for U+28AB5 𨪵 but the editors recognized the handwritten shape as ⿰金朐. Therefore, I suspect this is an one-off error and suggest pending more evidences.
