Investments in collectibles
and precious objects

Investments in precious coins, banknotes, stamps and medals will secure
the long-term growth of your capital stock and the distribution of risks into tangible assets.

There are several important reasons why it is prudent for investors to consider
the distribution of a part of their available resources into precious collectibles.

  • proved growth of the capital stock
  • distribution and reduction of risk - this way of investment is independent of the changes on the financial and commodity markets
  • enhancement of your investment portfolio
  • great advantage - global clientele from the USA, Europe, Russia, Near East, Japan, China and, recently, Singapore
  • no payments for maintenance
  • ideal family treasure and beautiful hobby

How to invest in precious specimens

Four key elements determine the market value and thus the investment
value of precious collectibles. These are:

  • –quality
  • rarity
  • place of origin
  • popularity

And what advice can we give you?

  • make certain that your piece of art is of a certain quality and preserved before you purchase it, determine your investment limit
  • buy the best specimens that you can afford in a given category
  • distribute your financial risks by buying specimens from various periods and cultures
  • do business with a leading auction house or a trader who is well informed about market
  • buy with caution
  • if possible, ask an expert for consultation

At the request of a client we purchased this extremely rare coin from the period of the rule of Maximilian I. We had been searching for this 7 ducat for 4 years. We had visited a countless number of collector fairs, auctions and private collectors from Los Angeles to Tokyo. Ours was a very attractive specimen, second of its kind in a private collection, in an impeccable condition 1/1 and with its history traced. ( collection Arthur Graf Enzenberg, auction Gilhofer & Ranschburg/Adolph Hess AG, Vienna 1936, number 142 ).

Due to its uniqueness this coin is much searched for by investors and collectors - truly, in 2012 it was sold for ca. 221,400 EUR (price including fees) and in 2021 its price based on supply is estimated at 500,000 EUR.

This 3 ducat from 1605 is a very precious item in the collector's portfolio. Ours is probably the only known specimen in a private collection in an impeccable condition 1/1 and with its history traced (auction number 100 LHS Numismatik Zürich, item number 1267).

In 2007 the coin was sold at an auction for ca. 76,800 CHF (including fees). Its estimated price in 2021 is 180,000 EUR. We believe that the client is very satisfied with this purchase.
