Plastic injection molding is VERY expensive (prices quoted are correct)
each cavity side will be multipled up in a tool set to produce 2,4 or 8
sets. So each ship is going to have to be pantographed up that many
times
into Tool Steel (long process if its an artistic shape)
The plastic set for the game 'risk' cost $45,000 to produce (in hong
kong
with cheap labour!!)
cf this with metal
from a master many silicone moulds can be cast , fill these with hot
lead
and when cool remove and re-use (no 100+tonne press required!)
The lead path is so simple many people can have a go and end up a co. 
'Prince august has a lot to answer for!!   ;-)
