Money and Equipment
Currency
Many traders use the barter system, especially between distant communities, but there is a somewhat standard currency.
Dollar
The dollar is a brass coin half an inch in diameter. By an amazing coincidence, it's worth about the same as one modern US dollar. It is often cut into half-dollars (or halves) and quarter-dollars (or quarters).
Gild
A small coin made of gold-plated tin. It is worth $10.
Red
Roughly square, flat sheets of translucent red crystal, about 1/8“ thick and half an inch in diameter. These are a byproduct of Heat Crystal mining. Reds are pretty much universally accepted on Everest, even though they can only be mined in Landing. Reds are impossible to counterfeit, because they're easily identified by the fractal pattern that appears when held up to the light. Reds are worth $100.
Blue
Hexagonal, flat sheets of smoky blue crystal, about an inch in diameter and 1/2” thick. While much more bulky than Reds, they have roughly the same value, and can be mined all over the world. Blues are worth $93-$100, depending on where they're traded.
Chip
A circular disk of extremely durable plastic, 1“ in diameter and and 1/4” thick. The technology to create hard plastics is no longer available, so these have become a valuable, portable currency. Chips are worth $1000.
Equipment
Basic gear
You can assume you have basic things like a change of clothes, enough food and water for one day of travel, a pouch or wallet to put your money in, a fire-starter etc. Anything beyond that has to be specifically listed on your character sheet, but if it's a cheap, mundane item, you can assume you have enough money to buy it without micro-managing your treasure.
Anything costing $10 or more has to be paid for out of your own money.
Surface survival
1 week's rations: $200
Ice gear – snowshoes, poles and well-insulated clothing. Very heavy, but necessary. $300

Small Heat Crystal – heats a well-insulated one-room house for two months: $1000
Large Heat Crystal – heats a larger house for two months: $2000
Sled – treated to withstand the cold and resist ice build-up: $200
Climbing gear – ropes, pitons etc, enough to get you out of the crater: $1000
Air bladder – a skin full of air. It's refreshing and sometimes necessary, but not a long-term solution: $5
Oxygen tank – enough air for a week: $150,000. $1000 to refill.
Fighting
Fighting equipment is abstracted. Describe it however you like!
Swords, daggers, bows and other weapons: $100
Light armor – reduces damage taken by 1, but reduces agility by 1. $100

Alchemy
Universal Salve – Heals any wound, giving you back 4 HP. $100
Fire bomb – A little red bead which will fly up to 500' to reach its target, where it explodes, dealing 1d6 damage. This is a black market item. $20
Glow stick – About as bright as a torch, but it produces very little heat and lasts for 3-4 months. $100
Flashlight – Very bright. It produces a cone of light in one direction, and typically lasts for 4-6 months. $400
Glider – If you strap yourself into this magical winged contraption, you can fly, and even carry one other person. It can manage about one trip out of the crater and one back in before it stops working. Good if you need to get somewhere in a hurry. $700
Food
Pork and beans are common and inexpensive.
Some pigs have been bred for long, fleshy ears. These are deep fried and sold as Elf Ears, the best of which can cost as much as $20 each, but there are more common varieties you can get for a couple dollars. You can also buy Elf Rinds, Elf Hocks, Elf Rump etc.
