Some weeks ago, I bought a collection of Angola. I knew it has a lot of mint included and it was a little bit disorganised. However when I got to work on it today, I was pleasantly surprised. The collection was very comprehensive and offered up lots of stamps I did not have beforehand. The early Crown issues were mostly good quality which is hard to find. I now have a quandary because there was a lot of mint and unexpectedly some highly catalogued singles and sets. I am going to have to see what to do with the mint stock!
