The one-dollar booklet pane, combining a single 9-cent "Dome of the Capitol" and seven of the 13-cent "Flag over the Capitol" adhesive, went off sale yesterday . The 11 x 10 1/2 perforation pane was produced for vending machine sale.

According to the Postal Service, there were 19,500,000 of the booklets produced. The booklet pane version of the 9-cent stamp is smaller than the normal sheetform version, and was printed on a whiter stock (Scott's No. 159). The 10 x 10 perforation variety which went off sale some time ago is not one of the hottest items on the hilatelic market. Assuming the printing ratio was two to one, it is possible that there were 13,000,000 of the 11 x 10 1/2 variety and only 6,500,000 of the 10 x 10.

The Bureau of the Mint's monthly report for August indicated that no Kennedy half dollars were struck for the second straight month. And, perhaps more important to collectors, the Mint did not strike any Eisenhower dollars during August.

Two years ago, in September of 1976, the Mint failed to produce either the dollar or the half dollar, but this was due to the transition from Bicentennial coinage to 1977 dated normal coinage. If the cutback in production of the dollar and 50-cent piece continues, and it apparently will, the 1978 mintages will be far below those of 1977.

Other subsidiary coinage was almost doubled from July to August. There were 101,076,000 Washington quarters minted, which is the highest total since March of 1978.

And Roosevelt dime output soared from 56,520,000 in July to 100,420,000 in August, but more came off the presses in May of this year. The previous high was 100,270,000 produced in june 1977.

The Lincoln penny production passed the billion mark for the first time in more than three years - at least an eight-year high. The Mint report indicates 1,032,490 pennies were minted during August.
