I found some information on the movie coins.

The Dimensions are as follows -

Galleon = 38.60 mm dia. = 1.52 inch
Sickle = 32 mm dia. = 1.26 inch
Knut = 25 mm dia. = 0.98 inch

Using the new Galleon diameter rounded to 1.5" and the
previous assumption of 5/64 inch thick, a 9 cubic foot
(3ft x 3ft x 1ft) pile of gold contains -

88,128 coins

or

US $705,024

UK £440,640

2 piles of coins = US$ 1,410,048

3 piles of coins = US$ 2,115,072

4 piles of coins = US$ 2,820,096

5 piles of coins = US$ 3,525,120

Take your pick based on Harry description of his
vault as he sees it for the first time. 

SIX percent interest on 3 piles of Gold is 

$126,904/year

No one else seems interested, but I thought it was a fun
excersize in determining just how rich Harry might be.

--- Quote: Philosopher's/Sorcerer's Stone ---

Griphook unlocked the door. A lot of green smoke came 
billowing out, and as it cleared, Harry gasped. Inside 
were mounds of gold coins. Columns of silver. Heaps of 
little bronze Knuts.

"All yours," smiled Hagrid.

All Harry's -- it was incredible. The Dursleys couldn't 
have known about this or they'd have had it from him 
faster than blinking. How often had they complained how 
much Harry cost them to keep? And all the time there had
been a small fortune belonging to him, buried deep under
London.

Hagrid helped Harry pile some of it into a bag.

'mounds of gold, columns of silver, and heaps of bronze'

So, we need to determine the Volume of 'mounds of gold'.

And, we need to keep in mind that we are averaging gold,
silver, and bronze into 'piles of just gold'. 

In the above example, 3 piles of gold, is actually one
pile that is 3 feet on a side (3ft x 3ft x 3ft)[1 cubic 
yard]. 

Is that a liberal or conservative estimate?

Two cubic yards, or 6 example piles, would be US$4,230,144.

Three cubic yards, or 9 piles, would be US$6,345,216. 

Between 3 and 9 piles of example gold seems about right.

Enquiring minds want to know.
