Can you explain what the reason is for needing another +$650 for matching serial numbers for your customers?
The difference between FOUR ROLLS of TWENTY that are not matching set numbers vs the FOUR rolls of twenty that are matching set numbers is 2 XMR ~ $330 and not +$650.Time/Organization is the reason.
When coordinating matching sets of 80 coins (4 rolls of 20) per order, it will take time
AND organization to do this. Keys need to be sorted for a particular random set # per order/customer.
Coins in the production process may have issues with the hologram getting damaged with key assembled or air bubbles when being assembled. Newly generated different keys needs to be printed with the missing numbers that had issues in production for matching sets, cut, and organized to account for the missing numbers and then reassembled.
For random numbered coins that are not matching sets, this is not the case as the key is discarded/destroyed and that particular number goes unsold for the time being.
It is too time consuming to create single sets for a customer at the moment to be sold individually.
Alternatively, customers can purchase non-matching rolls and possibly obtain a 4-coin set by mere chance.
Another clarification needs to be made:
QUESTION: Question: What does 26.5 XMR get me, 4 rolls of matching set and how many rainbow coins?
Answer:
You get 80 coins total (TWENTY 4-coin sets) that consist of:
ONE Roll of TWENTY 0.25 XMR Brass coins
ONE Roll of TWENTY 0.25 XMR Nickel Plated Brass coins RAINBOW
ONE Roll of TWENTY 0.1 XMR Brass coins
ONE Roll of TWENTY 0.1 XMR Nickel Plated Brass coins RAINBOW
The set numbers are randomly selected but each 4-coin set will be matching numbers.
