First off, the Aurora Isles lvls can drop a gold coin in the grass. Have seen it happen more than once on the same floor. (Jelly Farm 1 & 2, Stone Grove, & The Low Gardens)
Best luck at crafting would be the following with UV
Dragon Helm with Shadow Def High
Miracle Cloak with Normal Def High
Grey Feather Cowl with Normal Def Med
Acheron with vs Construct Dmg Med
Levithian with CTR of Med
Sinister Skelly Suit with Fire resist of Med
Divine Avenger with ASI of Low
All items were crafted by me and used for me. Haven't tried crafting just to get the UV I want or bought any UV's.
I also got 3 sun silver on one run once with 4 others. Who got none.
So I feel somewhat lucky.
Other lucky thing was to survive a complete t3 run with 3 arenas and severe lag.
I got 200 ce for 10.6k recently, score.
