<B>Undated<MS> Isle of Man Twentieth Noble--Brockage--PR64 ANACS.</B></I> KM-266 reverse. Platinum. This piece demonstrates the comprehensive nature of the Henderson Collection of Errors. This is the only error we have encountered struck in platinum. Minted in either in 1989 or 1992, this small coin (1/20th of an ounce) shows a full mirror brockage of the reverse. Apparently things were not going well the day this piece was struck as the brockage side shows evidence of a second error: a long, wide arc that appears to be a strike-through of grease or some other fine debris. Of course, in addition to the rarity of this piece in the carefully manufactured platinum coinage, this coin is even rarer as it was struck in proof format--a rarity factor that is self-evident in the overall production of coinage. The surfaces are bright and the proof fields are deeply mirrored. This brightness in the fields is also transferred to the brockage. An outstanding and extremely rare type of error. For the specialist, an error in platinum is not likely to be offered at public auction again any time in the near future.<BR><I>From The Henderson Collection of U.S. Gold Errors.</B></I>
