There are at least two types of 1909 VDB doubled die varieties. However, the one that is most desirable is the Type I doubled die obverse exhibiting prominent doubling in the inscription LIBERTY and in the first 9 of the date. This doubling is visible to the naked, but trained eye ' an important factor in making this a significant and highly collectible variety. Numismatic experts believe approximately 500 or so of these Type I doubled dies exist, and they command strong premiums above the prices of non-variety 1909 VDB Lincoln cents and are scarce in Brown, Red-Brown, and Red grades.
