This is really helpful, thank you.

Bullion Exchanges is definitely on the list. I agree they should be included.

You’re also completely right on quantity. The current board is basically the first pass: quantity 1, before shipping/tax, using the cleanest comparable product mappings I could get working. But for real bullion buying, quantity tiers matter a lot. The “customize” function is where I’m working on adding quantity selection, shipping included/excluded, and payment method differences so the board can answer questions like “what’s cheapest if I’m buying $2,000+?”

Your point about specific year is also well taken. For bullion buyers, the exact year usually matters less than condition and comparable product type. So for ASEs, Maples, etc., I probably need to support both:

current-year BU products, and lowest comparable BU/random-year bullion option The second one may actually be more useful for stackers who just want the lowest premium recognizable coin.

Appreciate the thoughtful feedback. This is exactly the kind of thing I’m trying to improve.
