Mounting
Place the mount upside down over a space on the sales book page, stick it to the top of the space with the self-adhesive gum, and place the stamp upside down in the mount, with the front of the stamp toward the page. If the mount is folded down firmly the stamp will assume its desired position on the page. When folding the mount, be certain that no adhesive is exposed to stick to the facing page.

Use of Mounts
We suggest placing only one item in each mount. We cannot photograph each item in a mount if they are stacked on top of one another, which then causes problems when a claim must be filed for substitution or damage. If you are not concerned about the loss, we can allow 3 to 4 items per mount. More than 5 items stacked in a mount will cause splitting at the seams. Do not place two separately priced items in one mount. This causes confusion for the buyer.

Hinging
Use new full hinges when placing stamps in sales books. Recycling hinges is not successful because the gum does not retain its sticking power. Sales books will be returned if used or partial hinges are used. When adhering the hinge, use more moisture on the portion connected to the page and less moisture on the portion connected to the stamp.

Pricing
Successful pricing of stamps (particularly U.S. material) is achieved by referring to dealers’ advertisements in the weekly philatelic press. Usually if items are priced 10 - 20 percent below the dealers’ prices of similar quality, this will result in the best sales. Do not anticipate a rise in prices a year from now when setting your prices today! Keep in mind that your material will be in competition with other members' material when pricing items.

Catalogue Order
Sales are generally better when items are mounted in catalogue, numerical order. In mixed country books, the countries should be mounted in alphabetical order.

Legibility
Write figures clearly and legibly so there is no question about an item’s price. Never write over a net price! If an error is made, remove the stamp and leave the space blank. Observe the printed decimal point and write dollars to the left, cents to the right. Do not use a line for 0 cents. Use ".00."

Comments
Leave 2/3 of the space blank so a member can apply his mark when purchasing an item. If you need to give a description (e.g., "thin," "crease," etc.) write it directly above the catalogue number and price.

Overlapping
Mount stamps one per space. Overlapping stamps may result in the damage or loss of your material. If there is excessive overlapping, your book will be rejected. Items could be removed without detection. It is preferable to have the whole stamp showing, but sets may be mounted with 2/3 of each stamp showing.

Sets
If entering sets for sale, read carefully the "Rules for Sellers" opposite page 14 of the sales book. If this practice is not done correctly, it will result in confusion for the buyer. We strongly suggest all of the stamps of the set on one page. Otherwise, clearly mark the set that continues onto the next page.

Duplication
The Sales Division suggests mounting no more than 3 copies of the same item in each book. Experience dictates that duplication results in poor sales.

Removing Pages
Pages 1 through 8 must remain in a book, even if there are no items on them, to maintain enough stiffness for safe handling.
