I think it's OK to grade this as Fair - probably bang in the middle of that grade range. If you're OK with coins in this grade, you could get quite a few Charles II's for under £100 (1662,3,4,8,71,2,3,6,7,9,80,81) plus 1695, 1696, 1707, 1708. You'll probably have to save up a bit for a Geo I & II (they rarely turn up ibelow Fine anyway - I don't think they circulated much).
