Lovely for detail but clearly polished within an inch of its life. I bought this one on eBay a couple of years ago for £175 inc P&P. They're out there if you're willing to wait.
Some 1970 sets sell for a premium as there were two dies used for the OBV on the Florin ,Halfcrown ,Sixpence and Half penny.
The Half penny is hard to find and collectors pay quite a lot more for one ,D of DEI too gap or I of DEI to tooth.
Always worth checking to see if you have one.
