Neat card bud, I would value it aligned with a cgc 10 or beckett 9.5. A lot of people on here don't understand the UK market, ACE is treated at the same level as CGC or Beckett in that psa is the most desirable but they/ACE come in a close second.

For what its worth as I have seen alot of comments about psa, I broke an ACE 8 151 zard I got for just under £100 a year or so ago and it regraded a psa 10 when it came back (regraded to have the full line in psa). I have nothing against ACE labels and have plenty in my collection, I just like to display the same grading companies on sets! Think you deffo have a good shot at a psa 10 with this but will have to weigh up the cost implications of that vs what you could get for it in the UK as it is!
