I hate to be the bearer of bad news, but nothing you have for sale on worth anything. The only item you have that is worth maybe 1fg is the extra equipment slots charm you have. You should make a mule and equip that charm.
There are 3 tiers of weapons, armors, and charms that you can use right from level 1. If you spend 1fg each on a tier 3 weapon, armor, and charm, you should be able to make it at least to level 5 in a flash without having to stop to regen. My cheap 3fg start of game setup involves a weapon with enhanced effect, an armor with 250+ max life, and a charm with 1-25+ life per kill.
If you're looking for items that are worth something, the most obvious is enhanced effect on anything. Armors and charms benefit from having added dexterity or strength. Staves or daggers with added intelligence can be worth selling too. It's also worth taking note of drops with magic luck, extra item slots, and sometimes high mana or life regen. Most of the other modifiers are most useful as extra additions to gear that already has the previously noted stats.
You can also sell higher levels of "white" items, or items that have no stats on them to people who throw them into the evil well.
People will also spend 1fg to buy items they will use to skill up their transmuting or glyphing.
If you explore a full catacombs, a map will drop. Some people will pay especially for maps with wells.
Some fishing rods and items like potions or comfreys can be sold for a little fg too.
Hope that helped!
