Silver bullion bars, how important is the condition?

I plan on buying a 10 ounce silver bar. I went to a shop and looked at some. A few were new and shiny and pictures stamped on, others were older and had some tarnish and had a simple stamp on them. What do I need to take into consideration when buying bars of silver?
The spot over price is $1.50

Bullion condition does not matter usually, because it is explicitly for investment purposes only. Silver jewelry is different and condition is everything. If you had your choice and there was no MAJOR difference in price, I would go with the shiner one personally.
