This is a set of Cook Islands 1935 stamps. They are SG 118-121. What's cool about these is that they are actually New Zealand Postal Fiscal Stamps, but they are Overprinted with "RAROTONGA" for use in the Cook Islands!
This is a lovely set!
These stamps are all Mint with Original Gum and in Very Fine condition. They are valued at L250 in the Stanley Gibbons Catalogue!
This item is over $100 USD so I will be shipping it using Priority Mail in the US, and Registered Mail overseas. This is to ensure that it reaches you in a safe and timely manner, and includes tracking!
