Thanks for opening this listing if you are seeing this from an app. please use the www. site so you see this whole listing with no limitations. Why buy from this seller? buy from this seller because you will get what you paid for with accurate and honest representation. I know it?s hard to buy things online you can not touch, try on, evaluate in person, etc. so please take the time to read this full description/terms view all pictures and address questions before bidding/buying. I am offering this before I take it to the refiner in hopes a collector will save it. You are buying a circa 1950s marked 10k yellow gold tie tack with The Enginerring Society of York Pa 1910 on the front. To make this clear the straight pin on the back is not gold nor is the clutch which are rarely gold. 99% of my items have a make offer option this piece does not because I am offering at my refiner value factoring in my selling fees. The condition is very good no stone chips or cracks, no metal wear or corrosion. BUYER pays insured shipping $5.50 USPS First Class Mail. INTERNATIONAL SHIPPING through Ship Global ONLY. I can combine shipping but best to let me invoice your before you pay to get an accurate price. Thank you for your time leaving feedback I prefer to leave feedback after buyer.
