Pennies, nickels, dimes, or what?
Average retail value is $790.00 for this coin in EF-40.
In my opinion they are the Liberty Seated Dollars: 1870cc, 1870s, 1872cc, 1872s, 1873cc, 1873s the Morgan Dollars: 1879cc, 1884s, 1889cc, 1892s, 1893s, 1895, 1897o, 1901, 1903s, 1904s the Peace Dollars: 1934s. All coins listed have values over $1,000.00 in the grade of MS-63. Dollar coins dated from 1971 to 2000 have no silver and most only have face value.
Any "Morgan dollar" that's 5 inches in diameter isn't real. You have some kind of copy, replica, or maybe even a privately-made bullion piece. Unless it indicates that it's made of silver (e.g. it says something like ".999 fine" on it somewhere) you'd need to have it examined in person to know what it is. And without an indication that it's made of silver, it's likely to be a base-metal replica.
