I have 28 postage stamps from Ethopia (unused, uncancelled) in varying denominations: 4 stamps shown in each photo. There are 4 marked 5c, 8 marked 10c, 4 marked 15c, 4 marked 20c, 4marked 25c and 4 marked 35c. Total is 480c. The 25c and 35c stamps are larger than the rest. Can you use these? Cash price is $ 8.00. Please call between 8am and 8pm.
