I was going through a box and I discovered some items that I had forgotten I had and I need to know if they're worth anything and any guess to what they may be worth,all are in ver excellent condition...If this isn't the right spot to ask this, please point me in the right direction:

LeGrand David Lecture Notes from the late 80's

Doug Henning World of Magic (like new)(picture on front cover of him sitting down with legs crossed in the clouds) Souvenir program

Siegfried and Roy Beyond Belief "An amazing spectacle" from Frontier Hotel&Casino Souvenir program

And picture holder for autographed picture from Frontier Hotel with Siegfried and Roy on cover...

Thanks for your help

I think right now, anything doug henning
is worth money. There's this resurgence
of him in the past year or so.

As far LeGrand David stuff, I have six
posters I've been trying to sell.

I just don't have a place for them.
I kept my favorite one. Along with the coin.
They were chosen for my mom from Cesareo.
