The mint does not drill holes into the coins. If a hole is drilled into a coin it dramatically reduces value. MANY COUNTRIES DRILLED HOLES IN THEIR COINS. THE COINS WERE WORN FOR JEWELRY AND THAT RENDERS THE COIN PRETTY MUCH WORTHLESS.
The four countries that still use coins with holes in them are Japan, South Korea, the Philippines, and Indonesia. These coins are known as "holey coins" and are typically used for denominations of 1 yen, 5 won, 1 piso, and 50 rupiah respectively. The holes in these coins serve both functional and symbolic purposes, such as making it easier to string them together or representing the country's cultural heritage.

Foreign coins usually cannot be used in other countries. You can cash in foreign coins, but you usually only get a fraction of the value when you do.
The practice of putting holes, specifically square holes, in currency originated in China. Holes were typically placed in 方孔錢 (fang kong qian) or cash, as it is refereed to in English, before China started using the recognizable round coin shape. Instead, cash was in the shape of a knife or a small spade prior to the use of round coins. The first known use of square holes in round cash as been dated to as early as 378 BCE. Since many countries in East Asia adopted Chinese currency systems because for their presence in the Chinese cultural sphere, these countries likewise used square-holed coins for at least some of their currency usage. These include Japan, Korea, and Vietnam. Some other countries, such as Brunei, were known to use Chinese currency before establishing their own systems. That being said, most of Southeast Asia either developed their own early currency systems or did not have a currency prior to European exposure, relying on barter.

The country of origin and the denomination of the coin would be a big help. Holes in the centre of coins is no longer as widespread a practice as it once was, although some countries continue to do so as a tradition.
Not sure about the other countries but Canada has one.
The name beside a harp on euro coins is ÉIRE. That is the Irish name for Ireland, and the coins with it on it are Euro coins from Ireland. They are accepted in any of the countries that use the Euro. Other countries would have different symbols and words on their Euro coins.

Assuming you mean "Which coins must you have if you have 30 coins that add to $1.09 c", there are a large variet of possibilities that largely depend of the country the coins come from. This is because different countries have different denominations of coins.
They don't have holes in them. People do that to wear them as jewelry, and it completely destroys the value.
