| 正面描述 | This piece is a countermarked issue struck upon a Brazilian 6400 Reis host coin of the appropriate denomination. Classification as KM#3 (rather than KM#2) is determined strictly by weight: specimens must weigh 14.3 g (the original host coin standard), approximately 13.21 g (the accepted average for countermarked examples), or no less than 12.61 g; pieces falling below this threshold are assigned to KM#2. Multiple 'G' countermarks are applied at intervals around the coin's periphery as an anti-clipping measure, though the absence of continuous perimeter coverage frequently allowed marginal clipping, reducing many specimens to KM#2 weight. The host coin obverse may bear the effigy of any Portuguese or Brazilian ruler active during or prior to the period of issue, as the countermarking authority was indifferent to the specific monarch portrayed provided the host denomination was correct. Significant wear, clipping, and gold dust extraction are characteristic of surviving examples, making well-preserved specimens of the requisite weight considerably scarce. |

| 背面描述 | The reverse retains the residual design of the Brazilian 6400 Reis host coin upon which the countermarks were applied. The specific reverse type varies according to the particular host coin used, and may display the Portuguese royal arms, crown, or other dynastic devices standard to the 6400 Reis denomination across the reigns of multiple monarchs. The field typically shows considerable wear and may exhibit evidence of clipping at the periphery. No standardised reverse type exists for this issue, as the countermarking authority imposed no restriction on which specific 6400 Reis reverse type was acceptable as a host. |
