I'd save the best of what you have for outdoor skating, and get rid of the rest.. if they are truly broken down they're really not of much use to anyone, beginner or not. If they're not fully broken down that might be different, but as you describe them that way I worry that they are toast - since I've been teaching LTS nothing bothers me more than seeing someone struggle in a broken down pair of skates they just bought used when they are not really any better than rentals, aside from offering some consistency over wearing a different pair of skates every week.
I know it seems wasteful, but skates are a consumable product like shoes - you wouldn't try to sell a pair of worn out running shoes, skates aren't really much different.
