Question for PAC-MAN Experts

Edit: I am really curious about this value-for money proposition, as I am not really a PAC-MAN fan (I really like it, though), but I would like to make a buck out of it (and maybe keep the sculpture for myself :))

How much would you say the following combo could be worth:

Timex T80 PAC-MAN 40th anniversary Edition (golden) - brand new (with tags)

Orlinski vs PAC-MAN red 10 cm sculpture (only plate signed) - new (in original sealed box)

PAC-MAN original keychain (red) - new in original package

?

I've seen this pack for sale online for a bit less than 600 dollars (shipping included). I researched and maybe the Timex and the keychain could sort of pay for the sculpture, but I am not sure.

Thanks in advance!

EditS: for clarity.
