Thanks, Guardian. A couple of notes:
The topiary that's listed there is not the kind you make from hedges. Already checked on that. Also, granite has a miniscule value for the turn-in, not in keeping with its rarity. (Normal granite through gold granite are each worth less than one point, and it takes 25 pieces of normal granite to make 1 point. Didn't have enough granite on Test to determine the rest of the values through gold. However, agapite was worth about 1.5 points per piece, so verite and valorite should be worth more.)
I think the UOGuide information listed for ML gems is incomplete. I believe some of the ML gems (e.g., amber) may be worth more than 25 points.
Also, don't forget that a lot of crafted stuff has value. For example, an agapite butchers war cleaver one of my chars had was worth 900 points. A verite enhanced monster loot shield was worth a couple hundred points. A bamboo flute another char had was worth less than a point. Community collection items (e.g., birds of britannia talisman, gypsy headdress) were almost valueless. Can't turn in spellbooks of any kind, I think. So, if you don't have tons of arties or old give-away items laying around, you can also get some points turning in crafted or looted items.
