Yes. Nearly all U.S. coins are minted with the front and back sides oriented 180° apart. Just check your pocket change.
The image of a vertex at (x, y) would be (-y, x).
To find the image of the point (5, 4) when rotated 180 degrees about the origin, you can apply the transformation that changes the signs of both coordinates. Thus, the new coordinates will be (-5, -4). Therefore, the image of the point (5, 4) after a 180-degree rotation about the origin is (-5, -4).
(-1, -4) rotated 90 degrees anticlockwise
If the point (3,5) is rotated 180 degrees, it becomes (-3,-5).
If the point (3,5) is rotated 180 degrees, it becomes (-3,-5).
The front bears an image of the Barbados Coat of Arms and the back, an image of a flying fish.
If it's both upside down and reversed from left to right, it would be equivalent to the image rotated 180 degrees.
someone took a photo with the camera rotated 180 degrees. My mum does it all the time. Skweekah

Rotational symmetry is defined as the shape or image can be rotated some amount and it still looks the same. The image can be rotated to three different positions and it would look the same.
The front has a portrait of President Ulysses S. Grant. The back has an image of the US Capitol building.
The 1922 silver dollar coin known as the Peace Dollar features the image of Liberty on the front and an eagle on the reverse, not Apollo. A 1922 Peace Dollar in average circulated condition can be worth around its silver melt value, which fluctuates with silver prices. In mint condition or rare varieties, it can be worth significantly more to collectors.
