I would suggest that pricing be consistent with low numbered notes such that any notes within 1,000 of the changeover have a premium beyond simply being a "changeover" note.
Hypothetical example: Signature changeover at HPG3000000. HPF is valued at $10 in G.UNC. HPG <3M is valued at $30. HPG >3M is valued at $20. HPH is valued at $10. If you had HPG2999964, I would attach a premium to that, making it worth perhaps $50 or more.
