2 year old swallowed a coin

So my daughter is 2 and a half and she told me she swallowed money. I freaked out called a nurse hotline and was recommended to go to the ER in case it was a battery I know that's worse but my daughter knows money and isn't allowed to play with it but somehow she managed to get one I think I didn't see. So I have to go by what she said. she's acting normal just wondering if other moms went through this how did everything go ??? So nervous waiting for my husband to get home to possibly take her to the ER please any in put
