Most collectors will always prefer an Uncirculated note, and these notes command substantial premiums over lower grades. A note in UNC condition is generally worth up to ten times more in this condition compared with merely VG (Very Good). An UNC note can be worth three times as much as a VF one. For notes seldom found in uncirculated condition, the premium may be even higher. The difference between Gem Uncirculated and Uncirculated can also be substantial. As a result, buyers are at risk of grade inflation, in that a dealer failing to notice a fold in an AU note and passing it off as UNC will undoubtedly feel justified in charging a higher price.
