It is simple math.
$15,000 give or take = a regular Sunday auction
$25,000 give or take = a regular Tuesday or Thursday auction
$250,000 give or take = a Mini/Major auction
$1,000,000 give or take = a Major auction
If the right collection comes along as a nucleus, I will have my 20th Major auction.
Until then, I am happy with exactly what I am doing!
