Our Services

     Put our decades of experience to work for you when purchasing large, complex, or valuable properties. The Harmers have been involved with some of the most valuable and complex philatelic transactions. Complex, multiple party purchases are often very difficult for the purchaser to self negotiate, as a trusted third party, Harmers is often able to pull all parties together for a mutually beneficial transaction.

Why Use Harmers

       Harmers can help you negotiate the sales price and conditions of sale for items you are interested in. We can assist with authentication of the items, terms and delivery of the item.

     By using Harmers, a purchaser can maintain their anonymity. Under certain situations and with certain buyers a better price on an item can be found if the true identity of the buyer is not know to the seller.

     Some complex, multi party transactions require a trusted, third party to coordinate the needs of multiple buyers and sellers. For decades Harmers has filled this roll, bringing diverse parties together with as much speed or patients as the situation demands.

Put our integrity and creativity to work for you by contacting us by telephone or e-mail.
