Are these coins real or replicas?

I got these coins from the gift shop in the Oxford University Museum of Natural History in Oxford, England about 7 years ago. They're Roman coins, I believe. I don't know if these are replicas or real (stupidly didn't ask). I assume they're replicas because they were cheap, and intuitively, coins from ~2000 years ago should be expensive, but I don't know much at all about Roman coins. Maybe they're so common that they really are pretty cheap?

I assume they're replicas, but can anybody actually confirm? Either way, but especially if they're real, can someone tell me what the coins actually are?

Thanks!

They're reproductions made by Westair Reproductions Limited, you can find more info here: https://www.forumancientcoins.com/NumisWiki/view.asp?key=WRL

The two top coins are actually pretty good replicas, much better than what's being sold to unsuspecting tourists thinking they're getting a bargain in middle eastern bazzars.

Ah, okay, as I suspected. Thanks!

Since you seem to be an expert, how much would a real Roman coin cost? In the low cost range? I really don't even know an order of magnitude on it.

We have some of the replicas listed in exonumia:

N#342155

N#342154

N#245752

This is a very tricky question as a real Roman coin is a very wide topic, you can get low grade 4th century Roman coins for 1$ each. The large coins in your photos are 2nd century, an as and a dupondius (the one with the spiky crown), my favorite ancient coin type. Those start at about 30$ in low grade if the emperor can be identified and go up with grade/rarity. The one with the elephant is a Ceasar denarius, in such grade it would be around 500$. The gold color coin are aureus and start at about 1000$ and go up with grade/rarity.
