In the 1990's, I purchased fifteen coins from Blanchard and Company, Inc. based on their claims that the coins would greatly increase in value over time. I interacted with 3 different account managers on multiple occasions, all of whom took advantage of my inexperience in rare coins and intentionally misrepresented the growth potential, while consistently overcharging me for the items I purchased.
Although this experience took place over 20 years ago, it continues to cause me great emotional distress, given that I entrusted several thousand dollars of my savings to these supposed professionals who turned out to be opportunistic, scam-artists. Indeed, I have only just discovered that the values of nearly all of the coins, as listed in the Numismatic Guaranty Corporation (NGC) and Professional Coin Grading Service (PCGS) price guides, are a mere fraction of Blanchard's original sales price.
At the time of purchase, the account managers represented that gains of 20% were expected for these coins. In reality, after 20 years, I am lucky if the coins are valued at 20% of the purchase prices I paid for them! In other words, instead of a 20% gain, I ended up with coins that are worth 80% LESS than what I paid for them!
