I note that since President Roosevelt removed the United States from the Gold Standard in 1933, the purchasing power of the dollar has declined by 95%.  In today's currency, the fine for not surrendering your private property (gold assets) would be approximately $200,000.
 
The Following are Excerpts from FDR's Executive Order:

"I, Franklin D. Roosevelt, President of the United States of America, do declare that said national emergency still continues to exist and pursuant to said section do hereby prohibit the hoarding of gold coin, gold bullion, and gold certificates within the continental United States by individuals, partnerships, associations and corporations"

"The term "hoarding" means the withdrawal and withholding of gold coin, gold bullion or gold certificates from the recognized and customary channels of trade"
