2. 1837 one schaling, Hamburg? 1.08g, silver?


3. Silver might be handcrafted ,19.6mm 1g


4.Silver might be handcrafted ,13.7mm 0.48g

1) This is a Dutch East India Company Duit, perhaps struck in Utrecht, although from my understanding it may have been struck in the mid-19th century with a 1790 date (much like the Maria Theresa Thaler); I don't do dutch coins, so that's all I know of it.

2) That's a Free and Hanseatic City of Hamburg schilling, with a mintage of about 153,000 (http://www.ngccoin.com/poplookup/WorldCoinPrices.aspx?category=67185&worldcoinid=186506)

3) Duchy of Julich and Berg, ruled as a part of the Electoral Palatinate, 1737, 1 Stuber, mintage unknown (http://www.ngccoin.com/poplookup/WorldCoinPrices.aspx?category=80137&worldcoinid=219160&FromSearch=true)

4) This is a "light Heller" of the Duchy of Julich and Berg, minted between 1640 and 1644, or in 1655; the date is either too faint in this picture, and my poor eyes can't read it, or it is undated, which is found also; mintage unknown (http://www.ngccoin.com/poplookup/WorldCoinPrices.aspx?category=101425&worldcoinid=266494&FromSearch=true)

I have many print resources on German States coins at my house, and I can try to see if mintages are in them for these coins when I get home tonight.

Hope this helps!
