Numismatics: Collecting Stellazzio and Getting the Hammer

Stellazzio coins are key items one can find around the world and trade in to an old bird (literally!) in Treno. This sidequest is very beneficial and can give some excellent items/equipment, as well as provide the infamous Hammer item used in making the best armor in the game. To boot, this can be done at any time, on any disc - nothing is missable! See below for the descriptions and screenshots explaining where they can be found, in the order in which they can first be found.

Locations

Aries	Dali, inside the windmill.
Cancer	Burmecia, behind a wagon just inside the city.
Gemini	Throw Gil into the fountain at the Treno entrance thirteen times (a total of 130 Gil).
Taurus	In the Treno slums, behind the item shop.
Scorpio	In Quan's Dwelling, near the bottom of the screen around the springs.
Virgo	In the bedroom of the inn in Black Mage Village.
Libra	Behind the fountain in Madain Sari.
Leo	In Alexandria Castle, back towards the far-right corner of the room with the statue of Neptune.
Sagittarius	Behind the grasses to the left of the pickle cart in Lindblum starting in Disc 3.
Capricorn	In the water down the right side path when entering Daguerreo.
Aquarius	In the entrance to Ipsen's Castle, in a chest up the right side shadows.
Pisces	In a chest on the left side at the core of the Invincible.
Ophiuchus	Ophiuchus can not be obtained until after the first twelve have been returned to Queen Stella. Once they are, she will discover the puzzle of the thirteenth coin and return the original twelve to you to help find it. It appears precisely where you once found Scorpio.

Rewards

These coins mean a great deal to Queen Stella, and as such you'll get a reward for each one you bring to her in Treno. You can bring them all at once, or one at a time, and in any order - the rewards are based on quantity, not specific Stellazzio. The one exception to this, of course, is the thirteenth Stellazzio, Ophiuchus; since you can not collect this stone until after all the others, it can not be given to Stella until last.

nth Coin Returned	Reward
1	1000 Gil
2	Phoenix Pinion
3	2000 Gil
4	Blood Sword
5	5000 Gil
6	Elixir
7	10000 Gil
8	Black Belt
9	20000 Gil
10	Rosetta Ring
11	30000 Gil
12	Robe Of Lords
13	Hammer

The Hammer

Cinna's Hammer is a weapon, but it's not one that can ever be used. Instead, it has two potential uses, depending on what your goals are for the game; if you're looking for Steiner's ultimate armor, you will need to take the Hammer to Hades' Synthesis Shop in Memoria to have it synthesized into Tin Armor. If you don't want to do that, just hold onto it and you'll instead get a short scene added into the ending, shown here!
