I have described the other. Which should be gold and it isn't. As such it is also certainly fake I am afraid.
The coin that is not an obvious match is the one you showed being silver? The one of the goose that is supposed to be gold clearly matches. What about the other one - with the dolphin - that is supposed to be gold as well?
"28 Karat Gold" --> yet you are "not trying to be a jerk" I think you kind of are if you consider talking down to someone rude.
You have to know Stevie. He really wasn't trying to be a jerk and actually was hoping your coins were real.
