Value of In-game Currency

[Antero]

If you were to walk into a regular market what would the value for these items be?
And if the currency hasn't been decided, could the public decide?

Meal: 5?
Low Tier - High Tier Sword: 200 - 2000?
Low Tier - High Tier Armour: 400 - 5000?
Basic HP Potion: 300?

Feel free to suggest even more items that your interested in knowing the value of.

Cheers, Iron Andero
