Hello Fitzy
Being new to collecting , I would start off with common HJ and DJ straps . the most common HJ shoulderstraps are the red piped # 565 , Blue piped # 663 and yellow piped # 663 ...You can find pairs of these still for $75 to 125 dollars depending on who is selling them . The DJ strap # 83 is also common ... you can find these for around $40 to 65 dollars each . For other HJ and DJ straps and insignia , expect to pay $125 up to $225 for a pair of numbered not so common straps . If you go to the uncommon straps for Gebiets in Berlin or Munich , Dresden ... Lettered straps such as RJF, AHS etc HJ leader straps with silver embroidered numbers or oakleaves ... expect to pay at least $350 dollars on up to the $1000s .
