Watch List notes:

Chile, pattern 2 centavos, 1890, struck over a silver 20 centavos of 1881, unique. 4.97 grams. Fascinating piece with copper-coin design struck over a silver coin from nine years prior (reason unknown) in nicely toned XF grade (hence probably circulated as a 20c despite the prominent "dos centavos" denomination), with much of the undercoin visible all over (particularly the date).

Estimate: $500 - 1000
