It’s an 1845 Victoria crown, graded MS63 by PCGS and very rare in this grade. But the surface, especially on the obverse, makes me wonder. Mike
I corrected the error in the text, so date there (1845) matches coin. Actually, there is a business strike 1847 crown. It's not as famous as the gothic proof and has a different design. It's also a beautiful coin (see pics below; it's MS62). The business strike in uncirculated grades is rarer than the gothic proof. It's not cheap but cheaper than the proof because of great demand of the latter. Mike
