No Silver Coins available AT ALL on the European server - or at least for the past 10 Months ?

I've seen some very odd Pets/Pet upgrades : 4* Air Tier II or III Pet with a SNORKEL & what appears to be a mixed 4* Fire+Water Pet ?
No Pet events since I started on Euros in July last year ... some players have a MASSIVE ADVANTAGE by getting such upgraded Pets , where they just aren't available for more recent starters ...
