1 Dollar - Elizabeth II Albino yellow fish

The "albino" designation here refers to a coin struck on an unplated or incompletely plated planchet, producing a washed-out, colorless appearance where applied color — in this case the yellow chromatic finish on the fish motif — is entirely absent. These are minting errors, not intentional variants, and KM#146 in its correct form is itself a relatively obscure Pacific wildlife issue with limited collector penetration outside Oceania-focused thematic collections. Albino errors on silver-plated copper-nickel pieces are particularly difficult to authenticate because the base planchet is indistinguishable from a simply worn or stripped example without close examination of the planchet's edge and surface texture.
