Buying How much are these sets usually worth (Sloppy, 7/11)?

[Alyx]

I am looking to buy the entire Sloppy series and the entire 7/11 series (including 24-hour-shop items, sandwich display, steamed-bun case, clerk shirt, and soft-drink display), but I'm unsure how much they are (usually!) worth in total.

How many IGB bells?
Or, alternatively, how many Bell Tree Bells? I would give all of my bells for these two complete sets, as I'd lost everything and these sets make me so happy.
