What starting date can a coin be considered for a mint error? 0

Before I send a coin in for a regrade for a mint error for rotated dies, I feel I need to ask at what starting date can a coin be considered a mint error? The coin I bought has been previously graded by NGC as XF45BN. It is a 1783 Washington & Independence "Unity" 1C. I bought it because I wanted it to add to my collection, but I didn't notice until after I purchased it that the reverse was rotated by 33 degrees. I am asking this question since the US Mint was not officially born by Congress until 1792, can it be considered a mint error since the US Mint did not actually exist at the time this coin was struck?

Rotations in pre-federal coinage are common enough that NGC would not note this on the label.

Thank you for the response. I know now that the previous submitter probably also found this out. I can now officially add this piece to my collection. Thank you!
