Enhancement Stones

[Triumph]

Alrighty...I've found this interesting for a long time, and I decided to get other opinions. I've seen enhancement stones go for the following:

Tier 1 Enhancement Stones:
Regular Elrue: 10-100c (average)
Regular Lix: 100-600c (average)
Regular Xir: 1s-2s (average)

Blessed Elrue: 1-2s (average)
Blessed Lix: 2-3s (average)
Blessed Xir: 5-6s (average)

Lucky Elrue: 1-2s (average)
Lucky Lix: 3-4s (average)
Lucky Xir: 3-5s (average)

For above prices, are they accurate? With all the new players...there's bound to be scams, lol.

And now for Tier 2. I personally have no clue. But I sold each type for the following today:

Regular Elrue: 6s each.
Regular Lix: 10s each.

Blessed Elrue: 10s each.
Blessed Lix: 15s each.

Lucky Elrue: 10s each.
Lucky Lix: 17s each.

Am I getting ripped off, or am I being extraordinarily lucky? Because I made 200s off like 25 stones lol.
