Only reason I am asking is that I have just found some old collectibles I bought a couple of decades back, all signed and sealed and have no idea what they are worth. I have the following:

1). Superman Fall Of Metropolis signed by Jerry Siegel, sealed, certificated and 135 of 585.
2). Amazing spiderman 30th Anniversary issue signed by John Romita SR sealed and one of 1000
3). Superman Forever hologram edition signed by 6 people cannot read their names one of 15,000 sealed
4). Star Wars trilogy boxed set signed by Roy Thomas, Frank Lopez and Carlos Garzon sealed.

Any ideas of value?

Thanks,
