PC on some g4s? (nfs)

[SunbeamV]

I was wondering about the values of some g4 brushables. I'm trying to catalogue my collection and include approximate replacement values, and I'm still familiar with approximate g1-3 values but I haven't been involved in any pony communities in a long time so I'm quite clueless about the few g4s I've collected. 

Muffin
Lyra Heart Strings
Lyrica Lilac
Ploomette (glitter wings)
Trixie Lulamoon (single)
Wysteria
Chrysalis
Nightmare Moon (not sure which multipack she's from)
Silver Spoon
Sunset Shimmer (single)
Sweetie Swirl

Thank you!

Bump. Have you tried looking at completed auctions on ebay?
