I suppose if I had expendable cash it might be something interesting to hang on the wall, but as an American, born and raised (and it really having no meaning here), I could not justify that kind of out-lay. Perhaps when I retire or maybe I could take up a family collection!!!
This is an oft-repeated myth, that somehow arms have no meaning in the USA, which is simply not true. Think of all of the arms of cities, counties, states and even the "Great Seal of the Republic", not to mention that there are many private citizens who are also armigers, including our first President and a number of his successors:

The US Army even maintains its own heraldic department to regulate the use of devices which are used by various units.

Time to but this old myth out to pasture.
