Nice pipes Mike! I have one Autograph and it's the first pipe I grab when I'm trying out a new English. That partial blast really makes the smooth grain stand out.
Very nice, and as far as I can tell the sandblasted ones are a bit cheaper so great on both accounts. I have thought about getting one but the expense and occassional offset bowl doesnt agree with me. Either way yours are still great congrats and keep enjoying.
The lower grades (4&5) generally run in the $300-$500 range. Grade 8s are usually around $600-$800. A 000 will generally be $1500 and up IF you can find one, they're pretty scarce. s and 5s tend to be partially or fully sandblasted. The high grades are more often smooth.
