All the toys, action figures, and other stuff that is considered memorabilia in the long-term? I should have kept in nice and secure in packaging. At minimum, buy two for your kid(s). A friend of mine supported himself, without a job for about 15 months, selling nothing more than comic books, action figures and the little bit he had in savings. His mortgage, car payment, and all the rest were kept current while he was jobless and it was all because of his collections.
