Beautiful table , I'd ask in a snooker forum for value.
That said when we closed our rehabilitation facility that had a large recreational therapy unit with 4 very expensive, full sized tables with 1 inch slate and all accessories we essentially had to give them away. They were not as beautiful as yours which might attract more buyers.....however the costs of professional moving and proper levelling after moving was upwards of $900 and that was 18 years ago.
Most pool tables I see Up here are either cheap or free......Kinda like antique pianos, I had a mint one from the mid 1800's that was appraised at $3500 but it took a year to sell and only got $600 , cost the buyers $450 to have it moved 20 miles.
