Let's get the totals of everything and then divide it. Once we total everything and give out shares then people can use their shares to buy items and parts of the dragons. I think we should give regular crew 4x the share. That will far from break the bank and it will boost morale.
Dragon skin and parts= 32,000
Magic items:
Gold: 6,000,000
Art, gems, precious items etc.:
Once we get the total we can take off the ships expenses and upgrades and then divide the shares.
