If they feel weird, they could be plated or polished, you did not specify enough details for us to determine if they are proofs or not, they very well could be.
Do you have a loupe? can you see circular marks all over the coin(they can be very faint, but are a sign of being polished)
hope this helps.
Also, did you get them from a coin shop or from CRH? If they were from an LCS, they should be real and most likely proofs, if they are from CRH, test them.
