This is from a rare group of Orange Free State Postal Fiscals from 1882-1890.  All of them are mint issues.  This one is SG F2, the 6d Purple Brown, and it is in Mint Original Gum and Fine to Very Fine Condition with some hinging.  An absolutely stunning find.

This item is over $100 USD so I will ship it using priority mail in the states and registered mail overseas.  This is to ensure that it reaches you in a safe and timely manner.
