We can help with the identification and what the catalogues say they might be worth. This should give you some help.

The condition the coin is in determines a great deal of the value - a common coin in excellent condition can be worth just as much, if not more, than a rare coin that's worn flat. The prices I quote below are for "Very Fine" condition, which I'm guessing is "typical condition" for these coins; if you want a more precise value, we'd have to see a photo or scan.
The KM numbers I quote are the reference numbers from the Krause catalogue of world coins.
Coin 1: It's Portuguese, but the date can't be "1861" -
Queen Maria II died in 1853. Might I suggest 1851 or 1841 for the date? In any event, the coin's denomination is denoted by the "X", which is the Roman numeral "10" - this is a 10 reis coin. Probably around $5, depending on date and condition. Either KM#
470 (1837-1839) or KM# 481 (1840-1853).
Coin 2: Again, have a closer look at the date - it can't be 1860 because Italy didn't completely unify and strike coins until 1861. While you're looking closely, look for a mintmark under the wreath - your possible options are none, H, N, M, OM and T. Values typically around $4, again depending on date and condition. KM# 11.
Coin 3: This one seems to be slightly scarcer than the other two: catalogue value $10 for typical (VF) grade. KM# 674.
