1958-D 50C MS66 Full Bell Lines. This was the final year that the Mint issued mint sets in cardboard holders with lots of sulphur to tone the coins. Tomaska noted: "Beautifully toned MS66 FBL and MS67 FBL 1958-D Franklins are usually among the most captivating coins in a top Franklin set. The colors are often dramatic - shimmering iridescent 'Peter Max' rainbows on the most spectacular pieces." A nearly perfect strike, practically flawless surface preservation, and attractive, slightly understated toning combine to make this Franklin half dollar an ideal type coin. One of the best preserved and prettiest mint set Franklins one of likely to set eyes on, this is a Premium Gem Franklin with likely mint set origins of this difficult late-series issue. This outstanding example is sharply detailed with a thin arc of colorful splashes of marvelous rose, orange, and lime-green iridescence captivating the viewer and enlivening both the obverse and the reverse rims. Vibrant, satiny, cartwheel mint luster illuminates the clean, colorful surfaces, and the strike is quite bold. Superbly defined, the excellent strike transcends the Full Bell Lines to include the lettering on the bell. Even among the normally well preserved mint set half dollars from this year, probably the source of this coin, only a small number of survivors could compete with the technical merits of this exceptional piece. The 1958-D Franklin Half dollar is the most available date of the series in Superb (MS67) Gem condition, because of its typically sharp strike. Still, Superb Gems with Full Bell Lines are quite rare. I'm happy with a well struck and magnificently preserved Premium (MS66) Gem that has spectacular eye appeal due to its vivid toning. A lovely specimen of this first year of the type issue.
