One issue with silver rounds, and bullion is that in dire circumstances, when some [bleep]-kicker is selling eggs from his wife's little flock, will he recognize the value of the rounds and/or bullion as true silver?
Ignore the fact that silver rounds aren't really worth it to fake. He might not know that. He is more likely to recognize that your pre-65 dimes and quarters are mostly silver. Easily recognizable and in a denomination that's easy to deal with.
This is why junk silver gets accorded a premium in the marketplace. Your Morgan silver dollar is generally acknowledged, by the non-collector or the unknowing to weigh an ounce. In reality a troy oz weighs 31.something grams. An Imperial oz is 28.something grams. Your US silver dollar weighs 26.something grams.
Despite this, if you've got a silver dollar in your pocket you're generally acknowledged to have an "OZ" of silver.
