Hi Miguel,
I would spend the time looking at the pieces if you like though I suspect there is little to be learned there of actual value. Please also beware of the "good stuff in the back room" sales technique.
If shopkeepers have good stuff, they will likely display it in the "front room," or it will have already been sold to a knowledgeable collector.
There is also the wonderful tale about the
"noble family who has fallen on bad times and must sell the family heirlooms." This is also often combined with,
"They need to do this quietly, without advertising because they don't want their friends/neighbors/relatives to know they need money badly."
"If you, as a smart collector can move fast enough.........."
Listen to their wonderful stories. Buy something cheap but fun. But unless you really know the pieces, odds are very great that you will buy expensive tourist pieces that were made to appeal to a "new" collector!
