Stanley Gibbons Currency Ltd Lists - When did they date from & to?

[Rob 3,152]

As the title says.

I picked up a run of these on eBay recently (lists 26 - 37) Any clues as to when they were issued? They came with an SGC Ltd American mail bid sale from 1980 included, so think it might be around this time.

If it helps to jog someone's memory, pointers are as follows. Phone number is 01, so predates 1990. The price of an UNC 1/6 bank token was £35. A Mary groat aVF cost £50 and the reference is S2492. When did the numbers change in the 1970s/80s?

Thanks.

My 1976 Seaby lists a Scarborough Siege crown for 2492, so it must have been after that. It's not so easy for me to check my 1980 and 1985 Seaby's right now, but if the answer doesn't arise I'll have a look tomorrow.

(In 1976, Mary groats were S1884 and £30 in Fine. 18 pence tokens were £15 - £18 in EF.)

The numbers changed in June or July 1978, so they postdate this.

Why did you ask when the numbers changed if you already knew??

Anyway, while I still have the Seaby to hand to answer your question... in 1980 (1979 values) the Mary groats are £35 F and £120 VF, while the 1/6 tokens were £30 - £35 EF. Early 1980 would seem a fair guess then, especially as prices rocketed up just after.

Because I didn't know, but wasn't thinking when I posted. I don't have many years of the of the standard catalogue, but by sitting down and ploughing through all the Numismatic Circulars it was possible to make an educated guess. The milled silver at the time was using EMC or ESC reference numbers, but the gold changed over and never used any references other than Seaby numbers.
