This particular set has a couple of interesting varieties: the 75c shows an over-inking of the plate at the base of the stamp and the 3b value is misperfed. 20,000 sets printed. The 10b high value is MNH. All others are between LM Mint and VLM Mint, a few with small hinge remnants. Note that this set is missing the 15c grey-black value.
