Hello @robissimio, yes cigars age very well when kept in the proper conditions (65-70% humidity). Some age better than others, milder cigars have the "risk" of losing some of their flavor as flavors can mellow over time, but this would probably take 5-10 years, and it's all personal preference.

Cigars will get more smooth as they age, and any edge on flavors will fade away. Even 6-12 months make a difference. Medium to full strength sticks can age well for decades.

Aged cigars, like wine, usually carry a premium on the secondary market. Some of the most sought after are many decades old. I have even seen cigars rolled in the 1890's for sale.

These two are my oldest, they were never anything fancy, the "coupons" cigar is 1930's era, and Hunter 1960's-1970's.
