A mole of something contains 6.02214179×10^23 of them, so a stack of one mole of pennies would be:
6.02214179×10^23 x 1 mm = 6.02214179×10^23 mm high.

12 x 3 / 4 = 9 The stack is 9 inches high.
It is physically impossible to fold a piece of paper in half more than 8 times. However, assuming you could do it (though it would be easier to cut the pile so far in half and put one half on top of the other), then: After 1 fold the stack has 2 sheets After 2 folds the stack has 4 sheets After 3 folds the stack has 8 sheets After n folds the stack has 2^n sheets After 50 folds the stack will be 2⁵⁰ sheets thick As each sheet is 0.1mm, the stack will be: 2⁵⁰ × 0.1 mm = 112589990684262.4 mm thick = 112589990.6842624 km thick ≈ 1.126 × 10¹¹ m thick
11 pennies. Each is about 0.9 cm thick.
A US penny is 1.55mm thick. Thus a stack of 1,000,000 pennies would be 1,550,000mm, or 1.55 kilometers (0.963 miles) high. A Canadian penny is 1.45mm thick. Thus a stack of 1,000,000 pennies would be 1,450,000mm, or 1.55 kilometers (0.901 miles) high. A post-1992 British penny is 1.65mm thick. Thus a stack of 1,000,000 pennies would be 1,650,000mm, or 1.65 kilometers (1.025 miles) high.
A US penny (US $0.01 coin) is 1.55 mm thick, so multiplying that by 15, a stack of 15 pennies is 23.25 mm or 2.325 cm tall

From the US Mint's website: a penny is 1.55 mm thick and 19.05 mm in diameter. So if you stack 100 of them, the 'length' of the stack will be 155 mm (6.1 inches). If you lay them flat, touching, then it would stretch as long as 1905 mm (75 inches - just over 6 feet).
A penny is .0625 inches thick, so if you had a stack of 534,000,000,000 (five hundred thirty-four billon) pennies, it would be 33,375,000,000 (thirty-three billion three hundred seventy-five million) inches high, which is 2,781,250,000 (two billion, seven hundred eighty-one million, two hundred fifty thousand) feet high. This would be 526,751.894 miles. In metric units, a penny is 1.55mm thick, so a stack of 534,000,000,000 pennies would be 827,700,000,000 (eight hundred twenty-seven billion seven hundred million) millimeters high. This would be 82,770,000,000 (eighty-two billion seven hundred seventy million) centimeters. That would be 827,700 km. A stack of pennies this size would go around the earth at the equator 21.1533778 times! Going by the average distance to the moon (384,400 km or 238,855 miles), a stack of pennies this high would go reach the moon and back with some pennies left over (the exact value is 2.205320776 times). 534,000,000,000 pennies=5,340,000,000 U.S. dollars (thats five billion, three hundred forty million). That would mean you are tied with or barely richer than Giorgio Armani at #144 on Forbes list of the world's billionaires. If you have 534,000,000,000 pennies don't stack them, turn them into dollars!
-- If you actually intended to type what you did type, then the answer completely depends on what kind of sack you use. -- If you actually intended to type "stack" instead of "sack" and didn't bother to proofread your own question for typos before you posted it, then . . . . . . . . The US penny is 1.55 mm thick. . . . . . The height of a stack of 100 of them is 155 mm = 15.5 centimeters tall.
The thickness of the US 1¢ coin is 1.55 mm. 100 of them in a stack rise to a lofty 155 mm = 15.5 cm.
really thick
Theoretically yes. The US had changed to "small cents" in 1857, when the flying eagle penny was introduced. Before that pennies were much bigger - about the size of a quarter, and thick. Starting with the 1857 flying eagle cent the pennies have been the same size since. Many Civil War tokens were made in the same size, some by grinding smooth a penny and engraving something patriotic on it. They are often called victory tokens. The flying eagle pennies were only made for three years, and were replaced by Indian Head pennies, which were made through 1908, when the Lincoln penny was introduced.
According to the US Mint the average thickness of a 1 cent coin is 1.55 mm. It's important to note that that's not an absolute figure. Huge numbers of cents are minted and at extremely high speeds, so variations in the minting process produce coins of different thicknesses. Collect a stack of pennies from your pocket change and you can see just how different some of them can be!
Ten pennies would be around 14.3 millimetres thick.
