Can you guys give me an idea of the value of any of these? I'm mainly interested in the 2 mark and the Chinese coin, the rest are just for curiosity sake.

One of the best ways that I know of getting a feel for the value is to search on eBay and then filter out the "SOLD" items. For example, for that 1917 German 1/2 Mark, you'll get this page: https://www.ebay.com/sch/i.html?_fr...+deutsche+reich&LH_Complete=1&rt=nc&LH_Sold=1 It gives you and idea of the range of prices. You can then compare the pics with yours to get a better match-up.
