Should anybody be in Ho Chi Minh City ( Saigon ), and be looking to visit Saigon Stamps & Coins shop .... They only sell coins on a Sunday. I didn't see this detail, when searching through the internet for info about what they might have in stock. It was only a 20 min. walk from the Intercontinental Hotel, but unfortunately, I attended the shop on a weekday, and they only had stamps in the shop - no coins. Also, the owner doesn't speak English, but he can write down a few words in English - such as "coins - Sunday".
