Ron Guth: The 1847 Half Dime is relatively common but not nearly as common as the 1841, 1842, 1844, or 1845. Uncirculated examples are readily available, but usually on the low end of the Mint State scale (from MS62 to MS64). Superb examples are much harder to find. The top of the Condition Census contains a single PCGS MS67+ (illustrated above).
Fully struck examples with full denticles are scarce and definitiely not the norm.
