This site lists stamps that I am selling from my personal collection. The collection ends with 1996 issues. At its peak, it consisted of most of the commemorative issues from the U.S., Republic of China, and the PRC. There are also quite a few bird and flower topical stamps from many countries.
You can add stamps that you are interested in onto a "shopping list" and then contact me with your list. I will verify that I have the stamps and then email you back with payment instructions. I accept credit cards via PayPal.
The collection contains many more stamps than those listed on this site. If you are searching for a particular issue, feel free to ask if I have it. If I have it, you can offer me a price.
