There were 7006 1934-D Oregon Trails minted and distributed at an issue price of $2.00 per coin. Interestingly, though the 1934-D Oregon is only the 10th "rarest" of the 14 Oregons, it is one of the toughest to find in Superb Gem condition. Only the very low mintage 1939 and 1939-S are harder to find in MS66 condition, and in MS67 the 1934-D is the rarest of all Oregons.
Though rare in superb condition, when they come the come nice. The strike on a Gem is sharp and the luster is usually outstanding. For some reasons, the 1934-D is more prone to bag marks than other Oregons, hence their rarity in Superb condition.
