I'll go first.
Yellow Submarine Macross SDF-1 Resin Kit 1/4000
This is the original kit from the original manufacture. I know this kit has been recast in Japan. But what is the original kit worth?
REVELL ROBOTECH SPACE FORTRESS SDF-1 Plastic Model Kit 1/5000
Produced in 1985 by Revell. Plastic parts molded by ARII. I see one on eBay (09/09/2010)for $249.99usd, but I'm sure this kit is worth far less.
Based on web research (09/10/2010) this kit is worth $25.00 - $100.00 usd.
REDS,INC Painted Poristone Model 1/24 Fighter Valkyrie, VF-1S Macross
This is the rarest Macross resin kit I’ve ever come across. This is the largest kit ever produced of the Valkyrie. It is over 1.5-feet long! Limited to a run of 300 units for sale in Japan only. I have no idea what this kit is worth in any condition.
This particular model has been damaged. It was accidently dropped. So to repair the damage it was put into rubber molds and recast. The duplicate parts were used to replace the damaged parts. Regardless due to its rarity I’m sure someday it will get a proper rebuild and paint job.
