Nguyen Ba Dam is the Vietnam's 'richest' man - at least that's what any coin collector will tell 
    you. The 78-year-old Hanoian boasts a collection of some 400 various rare coins and notes from both inside and out 
    side Vietnam, the oldest of which is a coin called Thai Binh Hung Bao, issued during the Dinh dynasty in 968. But 
    it's his Kien Phuc coin from Nguyen dynasty (1884) that Dam cherishes most. "A coin's age is not as important as 
    how rare it is. Some collectors may have older coin's but no one has the Kien Phuc coin that I have," said Dam, 
    adding that it's an extremely sought after coin among foreign collectors. Dam's collection also includes coins and 
    notes from more than 150 countries, most of which come from France, Italy and Denmark. It's taken Dam a lifetime 
    to amass such a collection, for which he's parlayed his background as a history teacher into his vast knowledge of 
    notes and coins. Today he's considered one of the country's foremost experts in the field.
    
    Humble beginnings
 
    
    Dam started collecting coins long before he was 10. At that time a small amount of money 
    went a lot further than it does today, as it only took a small note to buy a loaf of bread or catch a train 
    downtown. Despite of that, he tried to hold on to whatever money he could manage - even the smallest coins - and 
    he kept it all in a box instead of spending it. By the time he was 11 he had a sizeable collection stashed away 
    in his box. It was then that Dam visited the Louis Finot Museum (now the Natinal History Museum) with his older 
    brother and found that many of the coins on display there were identical to his. Dam realized he was sitting on a 
    fortune. Two important events shaped his development into the collector he is today. The first came when, while 
    in his late 30s, he was reading a copy of the Esperanto newspaper "Nun Tempa Bulgario" and saw a page asking 
    international money and stamp collectors to write in and seek trades. "This was my big chance," Dam recalled. So 
    he wrote to the address and sent a few sample notes and coins from his collection. Soon responses stared piling 
    in. Since then he's received more than 150 letters from foreign collectors looking to exchange notes and coins 
    with him and these inquires are still coming, often by the day.
    
    Fortune found
 
    
    But what really shaped Dam, is when a friend told him about an avid Hanoi collector named Duong. 
    Duong's family had once been one of the capital's biggest antique dealers, but by that point the antique trade was 
    illegal. Dam had caught wind of the fact that Duong was still holding on to a vast coin and note collection. Given 
    the times, though, Duong was cautious about discussing coins with anyone. But Dam set out to get his hands on 
    Duong's collection nonetheless. "I had to go to Duong's house several times before he'd even see me, and even then 
    he was hesitant. But finally, once he was willing to discuss his collection, he brought out a copper basin fill of 
    coins covered in a thick layer of mould. I was ecstatic and offered him VND 1,000 (at that time a two-storey house 
    was worth about VND 3,000) on the spot without even bargaining," Dam recalled. Duong agreed to let his collection 
    go, and Dam raised the money by selling some of his property and a few of his various antiques. The purchase more 
    than paid off, as it included the aforementioned Kien Phuc coin as well as a Canh Hung coin from Le Hien Tong 
    dynasty in the mid 1700s. "This purchase made me one of the country's riches collectors and gave me a large enough 
    collection to start swapping coins for notes, of which I had few at the time," Dam said. He soon befriended 
    another well-known collector, a printing factory director in the south named Pham Thang, and began exchanging 
    notes with him. Dam's collection mushroom from there.
    
    The Notorious Note
 
    
    Despite his age and the size of his impressive collection, Dam is still on the hunt for one 
    special note which, although he's gone to great pains to get his hands on it, has thus far alluded him. It's a 
    100 Indochina Dong note, issued by the Bank of Indochina in the former Saigon in 1983, that was printed in English 
    on one half of the face and French on the other. Dam said he had the same note, but printed only in French, which 
    is not nearly as rare as it's bilingual counterpart. So Dam's quest continues.
    
    Sell at no price
 
    
    Today Dam said he gets up to a dozen visitors a day, many of whom are experienced collectors 
    from at home and aboard who come to discuss the country's history and its legacy of coins and notes. "They are my 
    happiness," Dam said. "But I do not receive anyone looking to buy and sell. Such traders would spoil my day." 
    Despite the fact that many collectors would be willing to pay more than a thousand dollars per coin for much of 
    Dam's collection, he wants no part of it. "I'm only willing to part with pieces of my collection if I can upgrade 
    it through trading," Dam explained. "We [collectors] exchange notes and coins with each other, but we don't sell 
    them. I'm ready to give out a 16th century coin in exchange for one from the 19th century, as long as I feel it's 
    improving my collection, and sometimes I have to exchange 20 coin just to get the one coin I'm after." "It's not 
    the price - I could make a huge profit if I sold event just a few coins to interested buyers. But I think selling 
    one's collection loses the essence of what collecting is all about," said Dam, adding that he knew of only three 
    other people whom he considered the country's true collectors. "Collecting is about improving one's collection, 
    not about making money. To be a real collector, you must only think of your collection and how to develop it, not 
    about profit. That's what it's all about.".
