Will I want to sell all at once or in smaller lots?
The equation of buying silver is actually quite simple:
Bars = lower buying cost and lower sale price.
Coins =higher buying price and higher sale price.
This outcome was highlighted in the crisis of 2008. Despite silver bullion prices falling, a worldwide shortage of coins meant skyrocketing premiums.
In Australia the 1oz silver Kookaburra coins premium jumped from 25% over spot to a near 100% premium to spot in a matter of weeks.
This example highlights that coins often have two values: numismatic or scarcity premium and metal value.
Silver bullion bars only have metal value.
Hope this helps.....
