I have a gazillion covers in drawers, boxes and folders, yet I don't think I'm a cover collector! I do get drawn in by advertising/informational covers though, which are another thing that are fading into history. Here's a few of my favourites just for eye-candy

This is (despite the hopes and dreams of many deluded Ebay sellers), a very common Australian stamp issued in 1942. It was the standard postage rate, and 2.5 BILLION of them were issued between 1942 and 1950. The stamp on the left is a rarity though, although it looks almost exactly like the one on the right. Note how pale the King's face is? That's a process called "ink stripping", caused by over-inking of the ink roller during printing. This "White Face" variety is listed in mint condition, but the specialised catalogues don't price it used. I've seen a full mint sheet but never a used copy. MUH/MNH, the catalogue value is $250, mint hinged is $225. But there's more! Was it cancelled in a strange place called AY? No, it wasn't. In New South Wales from the 1910's to the 1960's, if a post office canceller couldn't be replaced quickly, an old canceller from another post office was utilised after some of the place-name had been removed. They're very collectable in their own right, but unfortunately I don't own the reference book for these and can't identify where the "AY" may have come from. Also, the "for comparison" stamp on the right, which I include in the sale, has an inverted watermark, found only in booklet stamps. Two common stamps that are a little bit different, listed for sale at $75. I can't remember what I had for lunch yesterday, but I remember this stuff!

Just saw this on FB. Collect what you like!

In another post I showed a Penny Black that I bought recently. It's replaced the one I had in my GB collection, so I'm selling my old one shown in the pic I chose not to list it on Ebay, where there's hundreds of Penny Blacks for sale and the competition is fierce, and listed it on a stamp forum instead. With a day to go on the auction, I've already recouped the amount I paid for the better stamp. I get a sale in three days, no merchant fees and money in the bank. Staying loyal to one platform is fine, but think horses for courses, regardless of what you're selling
