Just a guess, but #4 (possibly #5, too?) is some type of Roman silver coin, circa 1st century in Roman-occupied Israel? The hand looks typical of the artwork depicting the crucifixion of Jesus. Betrayed for 30 pieces of silver, etc. Or do you know that already and are asking which specific type of coin is shown there? Edit: Although a quick Google search tells me that, if that is what they are trying to depict, they are not historically accurate. http://www.forumancientcoins.com/catalog/roman-and-greek-coins.asp?vpar=808 #1-#3 seem more Medieval to me.
Nice call, @Numismat. Could it be this one, too? http://www.ebay.com/itm/SPAIN-GOLD-...GC-UNC-DETAILS-FERDINAND-ISABEL-/300880150437
