In
Spaceships, assuming that 'Matter/Antimatter' fuel is 50% of each, and that the matter is of negligible cost, antimatter costs $20 trillion per ton. That's about $22 million per gram (and ~$22,000 per milligram). Of course, a fuel tank to contain it costs no more than any other fuel tank,
Spaceships not being super-detailed. Given the other prices for fuel, antimatter-catalyzed fuel includes about 0.9 milligrams of antimatter per ton, and antimatter-boosted fuel (what this ship is shown as using) includes about half a gram of antimatter.
This implies that the antimatter destroyer with 9,500 tons of fuel carries perhaps 10 kilograms of antimatter, and thus 'only' go up in a 430-megaton explosion if the antimatter containment blows.
