May I suggest you find a way to cut costs, and offer the next coins as special orders?  Though not ideal for buyers, it means you don't have to hold inventory.   Or you could just have a few in inventory, then replenish as needed.

If you greatly lowered your golds, you might get some more orders.

Also consider a small deposit and the rest held in escrow, so people could feel comfortable now knowing your cash flow issues.  Otherwise you may have problems getting future preorders where people have to wait.

I also suggest more frequent updates to the community going forward.

Just a few suggestions if it helps.  I think your coins are beautiful and want to see your company continue making more.
