VERY interesting question. I don't personally have a good answer and will certainly be watching to see what others suggest. Of those mentioned thus far, my take is:
GLP - Perhaps worth a look. Yield is slightly more than MO, but I am somewhat chary of any company tied as closely to any commodity (oil in this case). Plus EPS somewhat erratic over last several years.
T - Not significantly larger than MO.
CLCT - I looked at the Value Line report on this one. Like GLP, the EPS history doesn't show the consistency I like to have in an investment.
YMMV. Please understand that no criticism is intended to those who supplied these suggestions. I sincerely appreciate them.
I like MO because it combines dividend yield with growth. I have been in MO for over 22 years, and it has returned over 17% per year (growth plus dividends). Not my best result, but good enough.
How about CLCT? pays 7%. No debt. #1 in two market categories. Great management. they certify and grade rare coins and trading cards. CLCT uses their dominance to raise prices and market share almost every year.
