This past weekend I scored 4 pounds 12 ounces of hallmarked pewter in a peddlers mall for $10.00. Last weekend I scored 5 pounds 2 ounces in various thrift shops for $19.00.
I got burned a couple of times when first starting to collect pewter. A couple of bucks for a lesson in pewter is one of the cheapest and best lessons I've had. Had zero problem chucking them in the trash.
If you are just beginning your pewter journey, I would recommend reading this thread in it's entireity. It takes a while but the knowlege contained herein is well worth your time.
For the beginner I would suggest only buying pieces touchmarked (hallmarked) and have Pewter plainly stamped on it. Pewter, ZINN, Tin, Etaine, SN, etc. Stay far away from Armetale, Wilton, pewterex, pewterine, etc.
I have found that pewtersmiths are proud of their craft, and they touchmark their pieces. If a piece has no touchmark and does not bend easily, I leave it where I found it. Candlesticks are filled with camel poo and glue, and in my experience, are never worth what you pay for them.
Learn to weigh pewter pieces by sight or touch. I Don't overpay for pewter, and my ground floor price that I will pay is about $6.00 per pound, as I can buy pewter from members on this site for that.
Good luck, and happy hunting.
