I am not done testing, but I have noticed a few oddities. Here is my testing so far (some of the notes might seem a bit jumbled, since some notes that should be general are listed under specific hammers) Also, I chose Lances because the maximum for Life and Mana Leech is 100%, so easy to tell if proper intensities are being reached.

Other Notes:
Bronze Hammers seem to handle the DI roll correctly, as I had a significant percent of items with DI of 41 - 47. This might be a result of the Bronze Hammer tending towards higher intensity rolls (info follows). It also seems that Bronze Hammers tend to have a very high percent of 80%+ intensities, and a very LOW percent of 60% - 80% intensities. Out of 50, only 2 had Hit Spell (including HLD & HLA) of less that 40%, and only 3 had Hit Life or Mana Leech of less than 80%, and that includes the one that has Mana Leech below the minimum. Also, when Mage Wep was rolled, it was always - 20 or -21.
AGAPITE HAMMERS (4 guaranteed properties)
Iron Ingots
50 Lances
15 Three Property Items
Not listed due to how long it would take, but still have posession of items on TC.
1 Low Leech Property
Hit Life Leech 59%
Faster Casting 1
Swing Speed 25%
Damage Increase 46%
Physical Damage 100%
Durability 130
Other Notes:
Agapite Hammers seem to handle the intensities more in line with what would be expected for a RNG roll between 65% and 100%. No particularly low, nor high, intensities stood out. This could be causing the result of a much higher percentage of "missing property" items vs. the Bronze Hammer.
GOLDEN HAMMER
Iron Ingots
50 Lances
21 Four Property Items
14 Three Property Items + 7 Two Property Items (21 Total)
8 Three Property Items that could be either 3 or 4 missing 1 (based on item durability).
(3 property items vs. 4 property items seems appropriate taking everything into consideration)

Other Notes:
Gold Hammer, like Bronze Hammers, seem to have a higher percent of high percentage intensity rolls. With Golden Hammers it is a bit of a lower intensity (mostly 75% and above, rather than 80% noted on Bronze Hammers). Also noted on both Bronze and Gold Hammers - Lost properties seem to have a higher likelihood of being due to a Durability roll, rather than a DI roll. However, it is difficult to tell how many missing properties are due to a Durability roll, since even without a roll on it, Durability can range all the way up to 255.
