John Zieman Jr. was born in Upstate New York in 1962. When he was 8 years old he started having an interest in coins, collecting with his grandfather and some help from his mother. After High School, he gave up collecting when he joined the US Army which he served honorably for almost 10 years. It was there where he met his wife of 28+ years and while living in Hawaii they had their only child Alexandrea. 
     It was not until 2004 when he regained interest in coins and started collecting with his daughter, Alexandrea. As beginning collectors he joined several Coin Clubs and even helped start the West Hernando Coin Club (WHCC) in 2007. 
     In July of 2008 John decided to start a small coin business called Z-man's Coins which he was assisted by Alexandrea. He started working in one Flea Market and through the next few years they worked 4 markets. John has also set up at a few Coin Club Coin Shows each year as well as going to many to buy and learn more about coins. John belongs to several Coin Clubs and enjoys taking part in activities with them. He was the secretary of the WHCC for almost 9 years, the secretary of the Pasco Coin Club for 3 years and Vice President(2015) for 1 year and President for almost 3 years(2016-present). John is very active with clubs and enjoys teaching and has given more than 30 formal presentations at these clubs. 
     John has also been the Bourse Chair and Board member for the WHCC for several years.
John has written several articles for Coin World and a couple awesome discoveries to include the Patterson family Collection, (2) 1943 Copper Cents, and a authentic Silver Indian Peace Medal. John is also a foremost authority on vintage slab holders and their values. He now works hard along side his daughter and wife working to improve his business, educate people on coins (especially youth), and giving back to those who need help.

     Alexandrea Zieman was born in Honolulu, Hawaii in 1995 and currently resides in Florida. Her numismatic story all started when she was just 8 years old. In 2004, her father, John Zieman, got a post card in the mail advertising a coin show. At first Alex was intrigued but thought that everyone collected coins. John clarified that it wasn't coins to be spent on bills and such, but coins that people collect as a hobby. 
     After a day at the Tampa Coin Show, she got a spark for the hobby and loved all the free things that the dealers gave to her. In 2008, John and Alex went into business together and she began dealing in coins at the age of 12. She learned about what coins were rare and valuable and how to educate customers. Alex also helped with forming a local coin club known today as the West Hernando Coin Club (WHCC).
     In 2012, that same club surprised her with a scholarship to the ANA Summer Seminar and for the next few years she continued to fly out to Colorado to take the classes. While out in Colorado, she learned how to grade and authenticate coins much better. Even when she returned home, she could not stop talking about how amazing the classes were so she took the position of Education Director at WHCC shortly after.
     Alex dedicated herself to numismatic research for years until 2015, she got the opportunity of a lifetime. She got offered a full time job at NGC. While at NGC, she was tasked with many jobs but remained hungry for knowledge and stayed after hours to learn vintage coin grading. It was not long until she was a coin grader herself and she was taught vintage coin grading under the feet of the masters at NGC.
     A while after leaving NGC, Alex gained employment at Heritage Auctions as a numismatist in their World and Ancient Coin Dept. Finding herself missing the thrills of being a self employed dealer, she returned after 6 months of working at Heritage.
     With now grading and auction experience under her belt, she is a much more experienced numismatist. Now she continues to attend various coin club meetings and give educational presentations. Her passion will never die and that spark has grown into an enormous flame that will hopefully light the way for new collectors to join the hobby.

     Danette Zieman was born in the Twin Cities of Minnesota in 1970. She grew up there and after high school she joined the US Army. She served honorably for 3 years. While in the Army she met John and after leaving the Army married him. They had their only child, Alexandrea, shortly after that.
     In 2012, Danette started helping with Z-man's Coins at Alexandrea's Flea Market booth. Danette started to take an interest in coins and joined the West Hernando Coin Club(WHCC). In 2015 Alexandrea left Z-man's Coins to work for NGC so Danette took over her booth at the Flea Market. Danette has also been the Vice President of the WHCC for a short time. Danette also joined the Tampa Bay Coin Club. Danette is a very friendly and cheerful person, anyone who has met her will agree. She brings plenty of joy to her customers and has many faithful followers that just enjoy her smile.
