U.S. 2¢ pieces were issued from 1864 to 1872.
The two-cent coin was a short-lived experiment that should have lasted far longer than it did, especially as a way to reduce the number of cents in circulation.
1 cent, two cent, three cent (two types), half-dimes, dimes, quarters, half-dollars, dollars ( gold & Silver), $20, $10, $5, and $2.50 gold coins.
No US two cent coins dated 1819 the first year was 1864. Please look at the coin again
There were 1863 2 cent pieces which were minted as pattern coins - test pieces to see what coins look like before a great number are minted and released into general circulation. The 1863 2 cent patten coins feature George Washington - the first time he appeared on a US coin and the interesting motto "GOD OUR TRUST" These pattern 2 cent pieces are quite rare and worth thousands of dollars. See the linked website for more. Also note that the coin is called a 2 cent piece rather than "2 cent penny", because a penny is the slang name for a 1-cent coin.
In the US there are pennies and there were 2 cent coins but they're not the same. Pennies are one cent coins. Two cent coins were made from 1864 to 1873, so please check your coin again and post a new question.
Sorry no US 2 cent coins dated 1863

10 coins= 2 fifty cent coins.
With US coins, a half-dollar and two nickels, or two quarters and a dime. If you have 20-cent coins, 3 of those, or the 50 cent and two 5 cent coins.

Germany uses coins that are based on the euro. There are two euro coins, one euro coins, 50 cent euros, 20 cent, 10 cent, 5 cent, and 1 cent euro coins.
In view of their minimal purchasing power, the Australian 1 and 2 cent coins had became virtually worthless and considering their value, they were relatively expensive to make. The last Australian 1 cent coins were put into general circulation in 1990 and the last 2 cent coins were put into general circulation in 1989. They were both progressively withdrawn from circulation in 1994 and all prices rounded off to the nearest 5 cents. The Australian 1 and 2 cent coins have not been de-monetised and are still considered to be legal tender and can be deposited in banks. According to the Australian Currency Act of 1965, 1 and 2 cent coins are legal tender if, when submitted for payment, they do not exceed a combined value of 20 cents. There may be problems in getting a business to accept them however. The one cent coin was minted for "Mint Packs" only in 1991. The two cent coin was minted for "Mint Packs" only in 1990 and 1991. The only decimal copper coins used in Australia were the one and two cent coins.

One way of doing this is with 19 ten-cent coins and 10 one-cent coins.
If your Australian 50 cent coins have been circulated, probably not much more than face value, since coins from most years are still in circulation. Individual coins have a value determined by the past year or two of buying and selling coins between dealers and collectors. Not all years of Australian 50 cent coins had "Proof" coins minted. A "complete" set of mint "uncirculated" coins could be valuable, but don't make plans for retirement. I recommend that you take your collection along to a reputable coin dealer will be able to give you an accurate valuation.
50 two cent coins, they exist.
