Here are some one liners...
China: A Tale of Two Currencies -- China needs their own money. Currently they are using barter and the people won't accept paper money so the government has given up and allowed silver to be used as money. I also discuss Silver Certificates and Andrew Jackson.
No Bull. Pamplona United Or Else -- The town of Pamplona is best known today for the "Running of the Bulls" but right now King Charles the 3rd of Naverre just wants them to stop killing each other. He knocks down the walls separating the three boroughs and forces them into a united city.
China: A Tale of Two CurrenciesEver since throwing off Mongol rule, China has been struggling to build an economy and especially a means of exchange. In other words... they needed their own MONEY! At this point most exchange is being done by barter. The Ming dynasty is issuing paper money as the Mongols had done before but it soon becomes worthless even though it can be exchanged for copper coins... theoretically. No matter how many laws they pass prohibiting using precious metals as the means of exchange, the people continue to use silver on the sly. In certain areas where barter is inefficient, a measure of silver called a tael [TAIL] (about 40 grams of silver) is now accepted as legal tender. This concession by the government will become the norm and the use of paper money will fall off over time. 
FYI: Tael [TAIL] is the English word borrowed from the Portuguese word, borrowed from the Malaysian word for "weight" and it is related to the word "tolerance" in the sense of "measuring."
